COMPOSITIONS AND METHODS TO CONTROL INSECT PESTS

REFERENCE TO SEQUENCE LISTING SUBMITTED ELECTRONICALLY

A sequence listing having the file name "6030WOPCT_SequenceList.txt" created on May 19, 2016 and having a size of 531 kilobytes is filed in computer readable form concurrently with the specification. The sequence listing is part of the specification and is herein incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to methods of molecular biology and gene silencing to control pests.

BACKGROUND

Plant insect pests are a serious problem in agriculture. They destroy millions of acres of staple crops such as corn, soybeans, peas, and cotton. Yearly, plant insect pests cause over $100 billion dollars in crop damage in the U.S. alone. In an ongoing seasonal battle, farmers must apply billions of gallons of synthetic pesticides to combat these pests. Other methods employed in the past delivered insecticidal activity by microorganisms or genes derived from microorganisms expressed in transgenic plants. For example, certain species of microorganisms of the genus Bacillus are known to possess pesticidal activity against a broad range of insect pests including Lepidoptera, Diptera, Coleoptera, Hemiptera, and others. In fact, microbial pesticides, particularly those obtained from Bacillus strains, have played an important role in agriculture as alternatives to chemical pest control. Agricultural scientists have developed crop plants with enhanced insect resistance by genetically engineering crop plants to produce insecticidal proteins from Bacillus. For example, corn and cotton plants genetically engineered to produce Cry toxins (see, e.g., Aronson (2002) Cell Mol. Life Sci. 59(3):417-425; Schnepf et al. (1998) Microbiol. Mol. Biol. Rev. 62(3):775-806) are now widely used in agriculture and have provided the farmer with an alternative to traditional insect-control methods. However, in some instances these Bt insecticidal proteins may only protect plants from a relatively narrow range of pests. Evolving insect resistance has also presented an issue (Gassmann et al. (2014) PNAS 111(14): 5141-6). Thus, novel insect control compositions remain desirable.

BRIEF SUMMARY

Methods and compositions are provided which employ a silencing element that, when ingested by a plant insect pest, such as Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest, is capable of decreasing the expression of a target sequence in the pest. In certain embodiments, the decrease in expression of the target sequence controls the ability of the pest to reproduce, and thereby the methods and compositions are capable of limiting damage to a plant or the spread of insect pests. Described herein are various target polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107-254, or variants or fragments thereof, or complements thereof, that modulate the expression of one or more of the sequences in the target pest RNAs involved in pest reproduction and fecundity. Accordingly, the various target polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107- 254, or variants or fragments thereof, or complements thereof, are useful in methods described herein to control target pests by insect sterilization and release of sterile target pests, i.e. , sterile insect technique ("SIT"). Also provided are silencing elements, which when ingested by the pest, decrease the level of expression of one or more of the target polynucleotides. Further provided are constructs encoding silencing elements and host cells comprising constructs encoding silencing elements. Plants, plant parts, plant cells, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof are also provided. Also provided are formulations of sprayable silencing agents for topical applications to pest insects or substrates where pest insects may be found.

In another embodiment, a method for controlling a plant insect pest, such as a Coleopteran,

Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest is provided. The method comprises feeding to a plant insect pest a composition comprising a silencing element, wherein the silencing element, when ingested by the pest reduces the level of a target sequence in the pest and thereby controls the pest. Further provided are methods to protect a plant from a plant insect pest. Such methods comprise introducing into the plant or plant part a disclosed silencing element. When the plant expressing the silencing element is ingested by the pest, the level of the target sequence is decreased and the pest is controlled. BRIEF DESCRIPTION OF THE DRAWINGS

FIGs. 1A-1D show representative data pertaining to sterilization of adult Western Corn Pvootworm ("WCRW") following ingestion of an artificial diet comprising a dsRNA construct comprising a target nucleotide sequence of SEQ ID NO.: 4. FIG. 1A shows the total number of eggs produced within 13-14 days by treatment and age group. For the younger female group, 50 pairs of male and female beetles were used, and for the older female group 50 mated female beetles were used. FIG. IB shows the average number of eggs produced per female/day during 13-14 day oviposition period by treatment and age group. The box plot graph is produced by Spotfire program indicating 4 quartiles, average, and 95% confidence interval of the mean. FIG. 1C shows the effect of various treatments, as indicated in the figure, on overall average egg hatch rate. Data represents 13- 14 days egg collection period; n = 6 replication/treatment/day; 5-45 eggs/replication depending on the day (p < 0.001). FIG. ID shows gene suppression analysis in WCRW adult beetles 8 days after treatment of female and male insects for younger age group and 4 days after treatment of female insects for older age group. Relative expression of VgR is shown from 4 individual insects for each treatment using the DV-RPS10 gene as reference and untreated older beetle as normalizer. Box plot shows 4 quartiles, average, median, and 95% confidence interval of the mean by treatment and age group.

FIGs. 2A-2B show representative data pertaining to sterilization of WCRW following feeding 3^rd instar larvae with an artificial diet comprising a dsRNA construct comprising a target nucleotide sequence of SEQ ID NO.: 4. FIG. 2A shows the average numbers and viable eggs produced per female. Eggs from 15-42 female adult beetles were counted for each treatment. The number in the box shows average numbers of eggs or viable eggs/female. The box plot shows 4 quartiles, average, median, and 95% confidence interval of the mean for each treatment. For the VgR dsRNA exposed group, viable egg production remain very low throughout the study period. Treatment with VgR dsRNA did not affect adult emergence. Mortality of adult beetles due to VgR dsRNA larval exposure was negligible. FIG. 2B shows VgR gene suppression analysis in 4 10-day old beetles and more than 15 28-day old beetles at Days 40 and 58 after treatment, respectively. Box plot of relative expression by qRTPCR shows 4 quartiles, average, median, and 95% confidence interval of the mean for each treatment in 10 and 28 day old beetles. Untreated 3^rd instar larvae were used as normalizer.

Overview

Methods and compositions are provided which employ one or more silencing elements that, when ingested by a plant insect pest, such as Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest are capable of decreasing the expression of a target sequence in the pest. In certain embodiments, the decrease in expression of the target sequence controls the ability of the pest to reproduce, and thereby the methods and compositions are capable of limiting damage to a plant or the spread of insect pests. Disclosed herein are target polynucleotides as set forth in SEQ ID NOS.: 1- 53 or 107-254, or variants and fragments thereof, and complements thereof. Silencing elements comprising sequences, complementary sequences, active fragments or variants of these target polynucleotides are provided which, when ingested by or when contacting the pest, decrease the expression of one or more of the target sequences and thereby controls the pest population via, for example, insect sterilization or through the application of sterile insect technique (SIT; i.e., the silencing elements are associated with sterilization activity). In some embodiments, a transgenic plant comprising a polynucleotide encoding silencing elements are provided which, when ingested by or when contacting the pest, decrease the expression of one or more of the target sequences and thereby controls the pest population via, for example, insect sterilization or through the application of SIT. In one embodiment, a method relates to producing sterile insects; releasing sterile insects into the environment in very large numbers (about 10 to 100 times the number of native insects) in order to mate with the native insects that are present in the environment, wherein the native female that mates with a sterile male produce infertile eggs. In a further embodiment, releasing sterile insects is repeated one or more times, wherein the number of native insects decreases and the ratio of sterile to native insects increases, driving the native population size downwards.

It is understood that target pest RNAs can be involved in one or more of male and/or female sterility, reduction of sperm count, egg production (fecundity), gender ratios, rates of fertilization (fertility), maturation of sexual organs, and sperm or egg viability. SIT has been used to control insect population by mating -based approach through release of sterile insects of one or both genders. In one embodiment, SIT comprises release of large number of sterile male insects that search for and mate with wild females, thereby preventing offspring. SIT using different schemes to generate sterile insects has been reported to control mosquito populations such as Anopheles or Aedes (e.g. , see Whyard, et al. (2015) Parasit. Vectors, 8:96; Benedict, M.Q. and A.S. Robinson (2003) Trends Parasitol. 19(8):349; and Nolan, et al. (201 1) Genetica 139:33). SIT has been field evaluated for population control of Aedes aegypti in Brazil (Carvalho, D.O. (2015), PLoS. 9(7): e0003864). Dengue, chikungunya, and now Zika virus are all transmitted by Aedes aegypti, one of the most widespread disease-carrying vectors on the globe.

In one embodiment, a method relates to producing sterile insects; releasing sterile insects into an environment in about 0.5, 1, 5, 10, 20, 30, 50, 60, 70, 90, to 100 times the number of native insects, wherein the sterile insects mate with the native insects that are present in the environment, and wherein the native female that mates with a sterile male produce infertile eggs. In a further embodiment, releasing sterile insects is repeated one or more times, wherein the number of native insects decreases and the ratio of sterile to native insects increases, driving the native population size downwards.

In one embodiment, compositions and methods are provided which employ a ribonucleic acid construct comprising at least one double-stranded RNA region, at least one strand of which comprises a polynucleotide that is complementary to: (a) a nucleotide sequence comprising a sequence of an RNA transcript expressed in a target pest, wherein the down-regulation of the RNA transcript results in increased sterility in the target; or variants and fragments thereof, and complements of said nucleotide sequence; (b) the nucleotide sequence comprising at least 90% sequence identity to said nucleotide sequence; or variants and fragments thereof, and complements thereof; or (c) the nucleotide sequence comprising at least 19 consecutive nucleotides of said nucleotide sequence; or variants and fragments thereof, and complements thereof; wherein the polynucleotide encodes a silencing element having sterilization activity against an insect plant pest.

In further embodiment, compositions and methods are provided which employ a ribonucleic acid construct comprising at least one double-stranded RNA region, at least one strand of which comprises a polynucleotide that is complementary to: (a) a nucleotide sequence comprising a sequence of an RNA transcript expressed in a Coleopteran pest, wherein the down-regulation of the RNA transcript results in increased sterility in the target; or variants and fragments thereof, and complements of said nucleotide sequence; (b) the nucleotide sequence comprising at least 90% sequence identity to said nucleotide sequence; or variants and fragments thereof, and complements thereof; or (c) the nucleotide sequence comprising at least 19 consecutive nucleotides of said nucleotide sequence; or variants and fragments thereof, and complements thereof; wherein the polynucleotide encodes a silencing element having sterilization activity against an insect plant pest.

In another embodiment, compositions and methods are provided which employ a ribonucleic acid construct comprising at least one double-stranded RNA region, at least one strand of which comprises a polynucleotide that is complementary to: (a) the nucleotide sequence comprising any one of SEQ ID NOS: 1-53 or 107-254; or variants and fragments thereof, and complements thereof; (b) the nucleotide sequence comprising at least 90% sequence identity to any one of nucleotides SEQ ID NOS: 1-53 or 107-254; or variants and fragments thereof, and complements thereof; or (c) the nucleotide sequence comprising at least 19 consecutive nucleotides of any one of SEQ ID NOS: 1-53 or 107-254; or variants and fragments thereof, and complements thereof; wherein the polynucleotide encodes a silencing element having sterilization activity against an insect plant pest.

As used herein, "VgR protein" or "vitellogenin receptor protein" refers to a family of large (180-214 kDa), membrane -bound proteins, and include proteins such as the VgR protein having the sequence of SEQ ID NO.: 106, and variants, homologs, and mutants thereof. It is believed that these proteins bind with high affinity to vitellogenin (K_d values of about 30-180 nM) and are involved in the cellular uptake of vitellogenin. VgR protein is typically expressed in ovarian tissue. As used herein, "BOULE" refers to a family of genes that encode a RNA binding protein with a highly conserved RRM (RNA recognition motif) domain and at least one DAZ (deleted in azoospermia) repeat of 24 amino acids rich in Asn, Tyr, and Gin residues. Deletion or mutations of BOULE in fly usually severely impair spermatogenesis. BOULE is required for meiotic entry and germline differentiation at the transition between G2 and M phases of meiosis. BOULE is typically expressed in germline cells.

As used herein, "VgR mRNA" or "vitellogenin receptor mRNA" refers to a messenger RNA transcript that when translated provides a VgR protein, or a variant, homolog, or mutant protein thereof.

As used herein, by "controlling a plant insect pest" or "controls a plant insect pest" is intended any effect on a plant insect pest that results in limiting the damage that the pest causes. Controlling a plant insect pest includes, but is not limited to, killing the pest, inhibiting development of the pest, altering fertility or growth of the pest in such a manner that the pest provides less damage to the plant, or in a manner for decreasing the number of offspring produced, producing less fit pests, including offspring, producing pests more susceptible to predator attack, producing pests more susceptible to other insecticidal proteins, or deterring the pests from eating the plant.

Reducing the level of expression of the target polynucleotide or the polypeptide encoded thereby, in the pest results in the suppression, control, and/or killing the invading pest. In one embodiment, reducing the level of expression of the target sequence of the pest will reduce the pest damage by at least about 2% to at least about 6%, at least about 5% to about 50%, at least about 10% to about 60%, at least about 30% to about 70%, at least about 40% to about 80%, or at least about 50% to about 90% or greater. Hence, methods disclosed herein can be utilized to control pests, including but not limited to, Coleopteran plant insect pests or a Diabrotica plant pest.

Certain assays measuring the control of a plant insect pest are commonly known in the art, as are methods to record nodal injury score. See, for example, Oleson et al. (2005) J. Econ. Entomol. 98: 1-8. Other assay methods are provided in the examples below.

Those skilled in the art will recognize that not all compositions are equally effective against all pests. Disclosed compositions, including the silencing elements disclosed herein, display activity against plant insect pests, which may include economically important agronomic, forest, greenhouse, nursery ornamentals, food and fiber, public and animal health, domestic and commercial structure, household and stored product pests.

As used herein "Coleopteran plant pest" is used to refer to any member of the Coleoptera order. Other plant insect pests that may be targeted by the methods and compositions disclosed herein, but are not limited to Mexican Bean Beetle (Epilachna varivestis), and Colorado potato beetle (Leptinotarsa decemlineata) .

As used herein, the term "Diabrotica plant pest" is used to refer to any member of the Diabrotica genus. Accordingly, the compositions and methods are also useful in protecting plants against any Diabrotica plant pest including, for example, Diabrotica adelpha; Diabrotica amecameca; Diabrotica balteata; Diabrotica barberi; Diabrotica biannularis; Diabrotica cristata; Diabrotica decempunctata; Diabrotica dissimilis; Diabrotica lemniscata; Diabrotica limitata (including, for example, Diabrotica limitata quindecimpuncata); Diabrotica longicornis; Diabrotica nummularis; Diabrotica porracea; Diabrotica scutellata; Diabrotica sexmaculata; Diabrotica speciosa (including, for example, Diabrotica speciosa speciosa); Diabrotica tibialis; Diabrotica undecimpunctata (including, for example, Southern corn rootworm {Diabrotica undecimpunctata), Diabrotica undecimpunctata duodecimnotata; Diabrotica undecimpunctata howardi (spotted cucumber beetle); Diabrotica undecimpunctata undecimpunctata (western spotted cucumber beetle)); Diabrotica virgifera (including, for example, Diabrotica virgifera virgifera (western corn rootworm) and Diabrotica virgifera zeae (Mexican corn rootworm)); Diabrotica viridula; Diabrotica wartensis; Diabrotica sp.

II. Target Sequences

As used herein, a "target sequence" or "target polynucleotide" comprises any sequence in the pest that one desires to reduce the level of expression thereof. In certain embodiments, decreasing the level of expression of the target sequence in the pest controls the pest. For instance, the target sequence may be essential for growth and development. Non-limiting examples of target sequences include a polynucleotide set forth in SEQ ID NOS.: 1-53 or 107-254, or variants and fragments thereof, and complements thereof. As exemplified elsewhere herein, decreasing the level of expression of one or more of these target sequences in a Coleopteran plant pest or a Diabrotica plant pest controls the pest. III. Silencing Elements

By "silencing element" is intended a polynucleotide which when contacted by or ingested by a plant insect pest, is capable of reducing or eliminating the level or expression of a target polynucleotide or the polypeptide encoded thereby. Accordingly, it is to be understood that "silencing element," as used herein, comprises polynucleotides such as RNA constructs, double stranded RNA (dsRNA), hairpin RNA, and sense and/or antisense RNA. . In one embodiment, the silencing element employed can reduce or eliminate the expression level of the target sequence by influencing the level of the target RNA transcript or, alternatively, by influencing translation and thereby affecting the level of the encoded polypeptide. Methods to assay for functional silencing elements that are capable of reducing or eliminating the level of a sequence of interest are disclosed elsewhere herein. A single polynucleotide employed in the disclosed methods can comprise one or more silencing elements to the same or different target polynucleotides. The silencing element can be produced in vivo (i.e., in a host cell such as a plant or microorganism) or in vitro.

In certain embodiments, a silencing element may comprise a chimeric construction molecule comprising two or more disclosed sequences or portions thereof. For example, the chimeric construction may be a hairpin or dsRNA as disclosed herein. A chimera may comprise two or more disclosed sequences or portions thereof. In one embodiment, a chimera contemplates two complementary sequences set forth herein, or portions thereof, having some degree of mismatch between the complementary sequences such that the two sequences are not perfect complements of one another. Providing at least two different sequences in a single silencing element may allow for targeting multiple genes using one silencing element and/or for example, one expression cassette. Targeting multiple genes may allow for slowing or reducing the possibility of resistance by the pest. In addition, providing multiple targeting ability in one expressed molecule may reduce the expression burden of the transformed plant or plant product, or provide topical treatments that are capable of targeting multiple hosts with one application.

In certain embodiments, while the silencing element controls pests, preferably the silencing element has no effect on the normal plant or plant part.

As discussed in further detail below, silencing elements can include, but are not limited to, a sense suppression element, an antisense suppression element, a double stranded R A, a siRNA, an amiPvNA, a miRNA, or a hairpin suppression element. In an embodiment, silencing elements may comprise a chimera where two or more disclosed sequences or active fragments or variants, or complements thereof, are found in the same RNA molecule. In various embodiments, a disclosed sequence or active fragment or variant, or complement thereof, may be present as more than one copy in a DNA construct, silencing element, DNA molecule or RNA molecule. In a hairpin or dsRNA molecule, the location of a sense or antisense sequence in the molecule, for example, in which sequence is transcribed first or is located on a particular terminus of the RNA molecule, is not limiting to the disclosed sequences, and the dsRNA is not to be limited by disclosures herein of a particular location for such a sequence. Non-limiting examples of silencing elements that can be employed to decrease expression of these target sequences comprise fragments or variants of the sense or antisense sequence, or alternatively consists of the sense or antisense sequence, of a sequence set forth in SEQ ID NOS.: 1-53 or 107-254, or variants and fragments thereof, and complements thereof. The silencing element can further comprise additional sequences that advantageously effect transcription and/or the stability of a resulting transcript. For example, the silencing elements can comprise at least one thymine residue at the 3' end. This can aid in stabilization. Thus, the silencing elements can have at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more thymine residues at the 3' end. As discussed in further detail below, enhancer suppressor elements can also be employed in conjunction with the silencing elements disclosed herein.

By "reduces" or "reducing" the expression level of a polynucleotide or a polypeptide encoded thereby is intended to mean, the polynucleotide or polypeptide level of the target sequence is statistically lower than the polynucleotide level or polypeptide level of the same target sequence in an appropriate control pest which is not exposed to (i.e., has not ingested or come into contact with) the silencing element. In particular embodiments, methods and/or compositions disclosed herein reduce the polynucleotide level and/or the polypeptide level of the target sequence in a plant insect pest to less than 95%, less than 90%, less than 80%, less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, or less than 5% of the polynucleotide level, or the level of the polypeptide encoded thereby, of the same target sequence in an appropriate control pest. In some embodiments, a silencing element has substantial sequence identity to the target polynucleotide, typically greater than about 65% sequence identity, greater than about 85% sequence identity, about 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% sequence identity. Furthermore, a silencing element can be complementary to a portion of the target polynucleotide. Generally, sequences of at least 15, 16, 17, 18, 19, 20, 22, 25, 50, 100, 200, 300, 400, 450 continuous nucleotides or greater of the sequence set forth in any of SEQ ID NOS. : 1 -53 or 107-254, or variants and fragments thereof, and complements thereof may be used. Methods to assay for the level of the RNA transcript, the level of the encoded polypeptide, or the activity of the polynucleotide or polypeptide are discussed elsewhere herein.

i. Sense Suppression Elements

As used herein, a "sense suppression element" comprises a polynucleotide designed to express an RNA molecule corresponding to at least a part of a target messenger RNA in the "sense" orientation. Expression of the RNA molecule comprising the sense suppression element reduces or eliminates the level of the target polynucleotide or the polypeptide encoded thereby. The polynucleotide comprising the sense suppression element may correspond to all or part of the sequence of the target polynucleotide, all or part of the 5' and/or 3' untranslated region of the target polynucleotide, all or part of the coding sequence of the target polynucleotide, or all or part of both the coding sequence and the untranslated regions of the target polynucleotide.

Typically, a sense suppression element has substantial sequence identity to the target polynucleotide, typically greater than about 65% sequence identity, greater than about 85% sequence identity, about 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% sequence identity. See, U.S. Patent Nos. 5,283, 184 and 5,034,323; herein incorporated by reference. The sense suppression element can be any length so long as it allows for the suppression of the targeted sequence. The sense suppression element can be, for example, 15, 16, 17, 18, 19, 20, 22, 25, 30, 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 900, 1000, 1 100, 1200, 1300 nucleotides or longer of the target polynucleotides set forth in any of SEQ ID NOS. : 1-53 or 107-254, or variants and fragments thereof, and complements thereof. In other embodiments, the sense suppression element can be, for example, about 15-25, 19-35, 19-50, 25-100, 100-150, 150-200, 200-250, 250-300, 300-350, 350-400, 450-500, 500-550, 550-600, 600-650, 650-700, 700-750, 750-800, 800-850, 850-900, 900-950, 950-1000, 1000-1050, 1050-1 100, 1 100-1200, 1200-1300, 1300-1400, 1400-1500, 1500-1600, 1600-1700, 1700- 1800 nucleotides or longer of the target polynucleotides set forth in any of SEQ ID NOS. : 1 -53 or 107-254, or variants and fragments thereof, and complements thereof.

ii. Antisense Suppression Elements As used herein, an "antisense suppression element" comprises a polynucleotide which is designed to express an RNA molecule complementary to all or part of a target messenger RNA. Expression of the antisense RNA suppression element reduces or eliminates the level of the target polynucleotide. The polynucleotide for use in antisense suppression may correspond to all or part of the complement of the sequence encoding the target polynucleotide, all or part of the complement of the 5' and/or 3' untranslated region of the target polynucleotide, all or part of the complement of the coding sequence of the target polynucleotide, or all or part of the complement of both the coding sequence and the untranslated regions of the target polynucleotide. In addition, the antisense suppression element may be fully complementary (i.e., 100% identical to the complement of the target sequence) or partially complementary (i.e., less than 100% identical to the complement of the target sequence) to the target polynucleotide. In certain embodiments, the antisense suppression element comprises at least 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence complementarity to the target polynucleotide. Antisense suppression may be used to inhibit the expression of multiple proteins in the same plant. See, for example, U.S. Patent No. 5,942,657. Furthermore, the antisense suppression element can be complementary to a portion of the target polynucleotide. Generally, sequences of at least 15, 16, 17, 18, 19, 20, 22, 25, 50, 100, 200, 300, 400, 450 nucleotides or greater of the sequence set forth in any of SEQ ID NOS.: 1-53 or 107-254, or variants and fragments thereof, and complements thereof may be used. Methods for using antisense suppression to inhibit the expression of endogenous genes in plants are described, for example, in Liu et al (2002) Plant Physiol. 129: 1732-1743 and U.S. Patent No. 5,942,657, which is herein incorporated by reference.

iii Double Stranded RNA Suppression Element

A "double stranded RNA silencing element" or "dsRNA," comprises at least one transcript that is capable of forming a dsRNA either before or after ingestion by a plant insect pest. Thus, a "dsRNA silencing element" includes a dsRNA, a transcript or polyribonucleotide capable of forming a dsRNA or more than one transcript or polyribonucleotide capable of forming a dsRNA. "Double stranded RNA" or "dsRNA" refers to a polyribonucleotide structure formed either by a single self- complementary RNA molecule or a polyribonucleotide structure formed by the expression of at least two distinct RNA strands. The dsRNA molecule(s) employed in the disclosed methods and compositions mediate the reduction of expression of a target sequence, for example, by mediating RNA interference "RNAi" or gene silencing in a sequence-specific manner. In various embodiments, the dsRNA is capable of reducing or eliminating the level or expression of a target polynucleotide or the polypeptide encoded thereby in a plant insect pest.

The dsRNA can reduce or eliminate the expression level of the target sequence by influencing the level of the target RNA transcript, by influencing translation and thereby affecting the level of the encoded polypeptide, or by influencing expression at the pre -transcriptional level (i.e., via the modulation of chromatin structure, methylation pattern, etc., to alter gene expression). For example, see Verdel et al. (2004) Science 303: 672-676; Pal-Bhadra et al. (2004) Science 303 :669-672; Allshire (2002) Science 297: 1818-1819; Volpe et al. (2002) Science 297: 1833-1837; Jenuwein (2002) Science 297:2215-2218; and Hall et al. (2002) Science 297:2232-2237. Methods to assay for functional dsRNA that are capable of reducing or eliminating the level of a sequence of interest are disclosed elsewhere herein. Accordingly, as used herein, the term "dsRNA" is meant to encompass other terms used to describe nucleic acid molecules that are capable of mediating R A interference or gene silencing, including, for example, short-interfering RNA (siRNA), double-stranded RNA (dsRNA), micro-RNA (miRNA), hairpin RNA, short hairpin RNA (shRNA), post-transcriptional gene silencing RNA (ptgsRNA), and others.

In certain embodiments, at least one strand of the duplex or double -stranded region of the dsRNA shares sufficient sequence identity or sequence complementarity to the target polynucleotide to allow the dsRNA to reduce the level of expression of the target sequence. In some embodiments, a dsRNA has substantial sequence identity to the target polynucleotide, typically greater than about 65% sequence identity, greater than about 85% sequence identity, about 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% sequence identity. Furthermore, a dsRNA element can be complementary to a portion of the target polynucleotide. Generally, sequences of at least 15, 16, 17, 18, 19, 20, 22, 25, 50, 100, 200, 300, 400, 450 nucleotides or greater of the sequence set forth in any of SEQ ID NOS.: 1 -53 or 107-254, or variants and fragments thereof, and complements thereof may be used. As used herein, the strand that is complementary to the target polynucleotide is the "antisense strand" and the strand homologous to the target polynucleotide is the "sense strand."

In another embodiment, the dsRNA comprises a hairpin RNA. A hairpin RNA comprises an RNA molecule that is capable of folding back onto itself to form a double stranded structure. Multiple structures can be employed as hairpin elements. In certain embodiments, the dsRNA suppression element comprises a hairpin element which comprises in the following order, a first segment, a second segment, and a third segment, where the first and the third segment share sufficient complementarity to allow the transcribed RNA to form a double -stranded stem-loop structure.

The "second segment" of the hairpin comprises a "loop" or a "loop region." These terms are used synonymously herein and are to be construed broadly to comprise any nucleotide sequence that confers enough flexibility to allow self-pairing to occur between complementary regions of a polynucleotide (i.e., segments 1 and 3 which form the stem of the hairpin). For example, in some embodiments, the loop region may be substantially single stranded and act as a spacer between the self-complementary regions of the hairpin stem -loop. In some embodiments, the loop region can comprise a random or nonsense nucleotide sequence and thus not share sequence identity to a target polynucleotide. In other embodiments, the loop region comprises a sense or an antisense RNA sequence or fragment thereof that shares identity to a target polynucleotide. See, for example, International Patent Publication No. WO 02/00904. In certain embodiments, the loop sequence can include an intron sequence, a sequence derived from an intron sequence, a sequence homologous to an intron sequence, or a modified intron sequence. The intron sequence can be one found in the same or a different species from which segments 1 and 3 are derived. In certain embodiments, the loop region can be optimized to be as short as possible while still providing enough intramolecular flexibility to allow the formation of the base-paired stem region. Accordingly, the loop sequence is generally less than 1000, 900, 800, 700, 600, 500, 400, 300, 200, 100, 50, 25, 20, 19, 18, 17, 16, 15, 10 nucleotides or less.

The "first" and the "third" segment of the hairpin RNA molecule comprise the base-paired stem of the hairpin structure. The first and the third segments are inverted repeats of one another and share sufficient complementarity to allow the formation of the base-paired stem region. In certain embodiments, the first and the third segments are fully complementary to one another. Alternatively, the first and the third segment may be partially complementary to each other so long as they are capable of hybridizing to one another to form a base-paired stem region. The amount of complementarity between the first and the third segment can be calculated as a percentage of the entire segment. Thus, the first and the third segment of the hairpin RNA generally share at least 50%, 60%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, up to and including 100% complementarity.

The first and the third segment are at least about 1000, 500, 475, 450, 425, 400, 375, 350, 325, 300, 250, 225, 200, 175, 150, 125, 100, 75, 60, 50, 40, 30, 25, 22, 20, 19, 18, 17, 16, 15 or 10 nucleotides in length. In certain embodiments, the length of the first and/or the third segment is about 10-100 nucleotides, about 10 to about 75 nucleotides, about 10 to about 50 nucleotides, about 10 to about 40 nucleotides, about 10 to about 35 nucleotides, about 10 to about 30 nucleotides, about 10 to about 25 nucleotides, about 10 to about 19 nucleotides, about 10 to about 20 nucleotides, about 19 to about 50 nucleotides, about 50 nucleotides to about 100 nucleotides, about 100 nucleotides to about 150 nucleotides, about 100 nucleotides to about 300 nucleotides, about 150 nucleotides to about 200 nucleotides, about 200 nucleotides to about 250 nucleotides, about 250 nucleotides to about 300 nucleotides, about 300 nucleotides to about 350 nucleotides, about 350 nucleotides to about 400 nucleotides, about 400 nucleotide to about 500 nucleotides, about 600 nt, about 700 nt, about 800 nt, about 900 nt, about 1000 nt, about 1100 nt, about 1200 nt, 1300 nt, 1400 nt, 1500 nt, 1600 nt, 1700 nt, 1800 nt, 1900 nt, 2000 nt or longer. In other embodiments, the length of the first and/or the third segment comprises at least 10-19 nucleotides, 10-20 nucleotides; 19-35 nucleotides, 20-35 nucleotides; 30-45 nucleotides; 40-50 nucleotides; 50-100 nucleotides; 100-300 nucleotides; about 500 -700 nucleotides; about 700-900 nucleotides; about 900-1 100 nucleotides; about 1300 -1500 nucleotides; about 1500 - 1700 nucleotides; about 1700 - 1900 nucleotides; about 1900 - 2100 nucleotides; about 2100 - 2300 nucleotides; or about 2300 - 2500 nucleotides. See, for example, International Publication No. WO 02/00904.

The disclosed hairpin molecules or double -stranded RNA molecules may have more than one disclosed sequence or active fragments or variants, or complements thereof, found in the same portion of the RNA molecule. For example, in a chimeric hairpin structure, the first segment of a hairpin molecule comprises two polynucleotide sections, each with a different disclosed sequence. For example, reading from one terminus of the hairpin, the first segment is composed of sequences from two separate genes (A followed by B). This first segment is followed by the second segment, the loop portion of the hairpin. The loop segment is followed by the third segment, where the complementary strands of the sequences in the first segment are found (B* followed by A*) in forming the stem-loop, hairpin structure, the stem contains SeqA-A* at the distal end of the stem and SeqB-B* proximal to the loop region.

In certain embodiments, the first and the third segment comprise at least 20 nucleotides having at least 85% complementary to the first segment. In still other embodiments, the first and the third segments which form the stem-loop structure of the hairpin comprise 3' or 5' overhang regions having unpaired nucleotide residues.

In certain embodiments, the sequences used in the first, the second, and/or the third segments comprise domains that are designed to have sufficient sequence identity to a target polynucleotide of interest and thereby have the ability to decrease the level of expression of the target polynucleotide. The specificity of the inhibitory RNA transcripts is therefore generally conferred by these domains of the silencing element. Thus, in some embodiments, the first, second and/or third segment of the silencing element comprise a domain having at least 10, at least 15, at least 19, at least 20, at least 21, at least 22, at least 23, at least 24, at least 25, at least 30, at least 40, at least 50, at least 100, at least 200, at least 300, at least 500, at least 1000, or more than 1000 nucleotides that share sufficient sequence identity to the target polynucleotide to allow for a decrease in expression levels of the target polynucleotide when expressed in an appropriate cell. In other embodiments, the domain is between about 15 to 50 nucleotides, about 19-35 nucleotides, about 20-35 nucleotides, about 25-50 nucleotides, about 19 to 75 nucleotides, about 20 to 75 nucleotides, about 40-90 nucleotides about 15- 100 nucleotides, 10-100 nucleotides, about 10 to about 75 nucleotides, about 10 to about 50 nucleotides, about 10 to about 40 nucleotides, about 10 to about 35 nucleotides, about 10 to about 30 nucleotides, about 10 to about 25 nucleotides, about 10 to about 20 nucleotides, about 10 to about 19 nucleotides, about 50 nucleotides to about 100 nucleotides, about 100 nucleotides to about 150 nucleotides, about 150 nucleotides to about 200 nucleotides, about 200 nucleotides to about 250 nucleotides, about 250 nucleotides to about 300 nucleotides, about 300 nucleotides to about 350 nucleotides, about 350 nucleotides to about 400 nucleotides, about 400 nucleotide to about 500 nucleotides or longer. In other embodiments, the length of the first and/or the third segment comprises at least 10-20 nucleotides, at least 10-19 nucleotides, 20-35 nucleotides, 30-45 nucleotides, 40-50 nucleotides, 50-100 nucleotides, or about 100-300 nucleotides.

In certain embodiments, a domain of the first, the second, and/or the third segment has 100% sequence identity to the target polynucleotide. In other embodiments, the domain of the first, the second and/or the third segment having homology to the target polynucleotide have at least 50%, 60%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or greater sequence identity to a region of the target polynucleotide. The sequence identity of the domains of the first, the second and/or the third segments complementary to a target polynucleotide need only be sufficient to decrease expression of the target polynucleotide of interest. See, for example, Chuang and Meyerowitz (2000) Proc. Natl. Acad. Sci. USA 97:4985-4990; Stoutjesdijk et al. (2002) Plant Physiol. 129: 1723-1731 ; Waterhouse and Helliwell (2003) Nat. Rev. Genet. 4:29-38; Pandolfini et al. BMC Biotechnology 3:7, and U.S. Patent Publication No. 20030175965; each of which is herein incorporated by reference. A transient assay for the efficiency of hpRNA constructs to silence gene expression in vivo has been described by Panstruga et al. (2003) Mol. Biol. Rep. 30: 135-140.

The amount of complementarity shared between the first, second, and/or third segment and the target polynucleotide or the amount of complementarity shared between the first segment and the third segment (i.e., the stem of the hairpin structure) may vary depending on the organism in which gene expression is to be controlled. Some organisms or cell types may require exact pairing or 100% identity, while other organisms or cell types may tolerate some mismatching. In some cells, for example, a single nucleotide mismatch in the targeting sequence abrogates the ability to suppress gene expression. In these cells, the disclosed suppression cassettes can be used to target the suppression of mutant genes, for example, oncogenes whose transcripts comprise point mutations and therefore they can be specifically targeted using the methods and compositions disclosed herein without altering the expression of the remaining wild-type allele. In other organisms, holistic sequence variability may be tolerated as long as some 22 nt region of the sequence is represented in 100% homology between target polynucleotide and the suppression cassette.

Any region of the target polynucleotide can be used to design a domain of the silencing element that shares sufficient sequence identity to allow expression of the hairpin transcript to decrease the level of the target polynucleotide. For instance, a domain may be designed to share sequence identity to the 5' untranslated region of the target polynucleotide(s), the 3' untranslated region of the target polynucleotide(s), exonic regions of the target polynucleotide(s), intronic regions of the target polynucleotide(s), and any combination thereof. In certain embodiments, a domain of the silencing element shares sufficient identity, homology, or is complementary to at least about 15, 16, 17, 18, 19, 20, 22, 25 or 30 consecutive nucleotides from about nucleotides 1-50, 25-75, 75-125, 50- 100, 125-175, 175-225, 100-150, 150-200, 200-250, 225-275, 275-325, 250-300, 325-375, 375-425, 300-350, 350-400, 425-475, 400-450, 475-525, 450-500, 525-575, 575-625, 550-600, 625-675, 675- 725, 600-650, 625-675, 675-725, 650-700, 725-825, 825-875, 750-800, 875-925, 925-975, 850-900, 925-975, 975-1025, 950-1000, 1000-1050, 1025-1075, 1075-1125, 1050-1100, 1125-1175, 1100- 1200, 1175-1225, 1225-1275, 1200-1300, 1325-1375, 1375-1425, 1300-1400, 1425-1475, 1475-1525, 1400-1500, 1525-1575, 1575-1625, 1625-1675, 1675-1725, 1725-1775, 1775-1825, 1825-1875, 1875- 1925, 1925-1975, 1975-2025, 2025-2075, 2075-2125, 2125-2175, 2175-2225, 1500-1600, 1600-1700, 1700-1800, 1800-1900, 1900-2000 of the target sequence. In some instances to optimize the siRNA sequences employed in the hairpin, the synthetic oligodeoxyribonucleotide/RNAse H method can be used to determine sites on the target mRNA that are in a conformation that is susceptible to RNA silencing. See, for example, Vickers et al. (2003) J. Biol. Chem 278:7108-7118 and Yang et al. (2002) Proc. Natl. Acad. Sci. USA 99:9442-9447, herein incorporated by reference. These studies indicate that there is a significant correlation between the RNase-H-sensitive sites and sites that promote efficient siRNA-directed mRNA degradation.

The hairpin silencing element may also be designed such that the sense sequence or the antisense sequence do not correspond to a target polynucleotide. In this embodiment, the sense and antisense sequence flank a loop sequence that comprises a nucleotide sequence corresponding to all or part of the target polynucleotide. Thus, it is the loop region that determines the specificity of the RNA interference. See, for example, WO 02/00904.

In addition, transcriptional gene silencing (TGS) may be accomplished through use of a hairpin suppression element where the inverted repeat of the hairpin shares sequence identity with the promoter region of a target polynucleotide to be silenced. See, for example, Aufsatz et al. (2002) PNAS 99 (Suppl. 4): 16499-16506 and Mette et al. (2000) EMBO J 19( 19): 5194-5201.

In other embodiments, the silencing element can comprise a small RNA (sRNA). sRNAs can comprise both micro RNA (miRNA) and short-interfering RNA (siRNA) (Meister and Tuschl (2004) Nature 431 :343-349 and Bonetta et al. (2004) Nature Methods 1:79-86). miRNAs are regulatory agents comprising about 19 to about 24 ribonucleotides in length which are highly efficient at inhibiting the expression of target polynucleotides. See, for example Javier et al. (2003) Nature 425: 257-263. For miRNA interference, the silencing element can be designed to express a dsRNA molecule that forms a hairpin structure or partially base-paired structure containing a 19, 20, 21, 22, 23, 24 or 25 nucleotide sequence that is complementary to the target polynucleotide of interest. The miRNA can be synthetically made, or transcribed as a longer RNA which is subsequently cleaved to produce the active miRNA. Specifically, the miRNA can comprise 19 nucleotides of the sequence having homology to a target polynucleotide in sense orientation and 19 nucleotides of a corresponding antisense sequence that is complementary to the sense sequence. The miRNA can be an "artificial miRNA" or "amiRNA" which comprises a miRNA sequence that is synthetically designed to silence a target sequence.

When expressing an miRNA the final (mature) miRNA is present in a duplex in a precursor backbone structure, the two strands being referred to as the miRNA (the strand that will eventually base pair with the target) and miRNA* (star sequence). It has been demonstrated that miRNAs can be transgenically expressed and target genes of interest for efficient silencing (Highly specific gene silencing by artificial microRNAs in Arabidopsis Schwab R, Ossowski S, Riester M, Warthmann N, Weigel D. Plant Cell. 2006 May; 18(5): 1 121-33. Epub 2006 Mar 10; and Expression of artificial microRNAs in transgenic Arabidopsis thaliana confers virus resistance. Niu QW, Lin SS, Reyes JL, Chen KC, Wu HW, Yeh SD, Chua NH. Nat Biotechnol. 2006 Nov; 24( 1 1): 1420-8. Epub 2006 Oct 22. Erratum in: Nat Biotechnol. 2007 Feb; 25(2):254.).

The silencing element for miRNA interference comprises a miRNA primary sequence. The miRNA primary sequence comprises a DNA sequence having the miRNA and star sequences separated by a loop as well as additional sequences flanking this region that are important for processing. When expressed as an RNA, the structure of the primary miRNA is such as to allow for the formation of a hairpin RNA structure that can be processed into a mature miRNA. In some embodiments, the miRNA backbone comprises a genomic or cDNA miRNA precursor sequence, wherein said sequence comprises a native primary in which a heterologous (artificial) mature miRNA and star sequence are inserted.

As used herein, a "star sequence" is the sequence within a miRNA precursor backbone that is complementary to the miRNA and forms a duplex with the miRNA to form the stem structure of a hairpin RNA. In some embodiments, the star sequence can comprise less than 100% complementarity to the miRNA sequence. Alternatively, the star sequence can comprise at least 99%, 98%, 97%, 96%, 95%, 90%, 85%, 80% or lower sequence complementarity to the miRNA sequence as long as the star sequence has sufficient complementarity to the miRNA sequence to form a double stranded structure. In still further embodiments, the star sequence comprises a sequence having 1, 2, 3, 4, 5 or more mismatches with the miRNA sequence and still has sufficient complementarity to form a double stranded structure with the miRNA sequence resulting in production of miRNA and suppression of the target sequence.

The miRNA precursor backbones can be from any plant. In some embodiments, the miRNA precursor backbone is from a monocot. In other embodiments, the miRNA precursor backbone is from a dicot. In further embodiments, the backbone is from maize or soybean. MicroRNA precursor backbones have been described previously. For example, US20090155910A1 (WO 2009/079532) discloses the following soybean miRNA precursor backbones: 156c, 159, 166b, 168c, 396b and 398b, and US20090155909A1 (WO 2009/079548) discloses the following maize miRNA precursor backbones: 159c, 164h, 168a, 169r, and 396h.

Thus, the primary miRNA can be altered to allow for efficient insertion of heterologous miRNA and star sequences within the miRNA precursor backbone. In such instances, the miRNA segment and the star segment of the miRNA precursor backbone are replaced with the heterologous miRNA and the heterologous star sequences, designed to target any sequence of interest, using a PCR technique and cloned into an expression construct. It is recognized that there could be alterations to the position at which the artificial miRNA and star sequences are inserted into the backbone. Detailed methods for inserting the miRNA and star sequence into the miRNA precursor backbone are described in, for example, US Patent Applications 20090155909A1 and US20090155910A1.

When designing a miRNA sequence and star sequence, various design choices can be made.

See, for example, Schwab R, et al. (2005) Dev Cell 8: 517-27. In non-limiting embodiments, the miRNA sequences disclosed herein can have a "U" at the 5'-end, a "C" or "G" at the 19th nucleotide position, and an "A" or "U" at the 10th nucleotide position. In other embodiments, the miRNA design is such that the miRNA have a high free delta-G as calculated using the ZipFold algorithm (Markham, N. R. & Zuker, M. (2005) Nucleic Acids Res. 33: W577-W581.) Optionally, a one base pair change can be added within the 5' portion of the miRNA so that the sequence differs from the target sequence by one nucleotide.

The methods and compositions disclosed herein employ DNA constructs that when transcribed "form" a silencing element, such as a dsRNA molecule. The methods and compositions also may comprise a host cell comprising the DNA construct encoding a silencing element. In another embodiment, The methods and compositions also may comprise a transgenic plant comprising the DNA construct encoding a silencing element. Accordingly, the heterologous polynucleotide being expressed need not form the dsRNA by itself, but can interact with other sequences in the plant cell or in the pest gut after ingestion to allow the formation of the dsRNA. For example, a chimeric polynucleotide that can selectively silence the target polynucleotide can be generated by expressing a chimeric construct comprising the target sequence for a miRNA or siRNA to a sequence corresponding to all or part of the gene or genes to be silenced. In this embodiment, the dsRNA is "formed" when the target for the miRNA or siRNA interacts with the miRNA present in the cell. The resulting dsRNA can then reduce the level of expression of the gene or genes to be silenced. See, for example, US Application Publication 2007-0130653, entitled "Methods and Compositions for Gene Silencing". The construct can be designed to have a target for an endogenous miRNA or alternatively, a target for a heterologous and/or synthetic miRNA can be employed in the construct. If a heterologous and/or synthetic miRNA is employed, it can be introduced into the cell on the same nucleotide construct as the chimeric polynucleotide or on a separate construct. As discussed elsewhere herein, any method can be used to introduce the construct comprising the heterologous miRNA.

IV Variants and Fragments

By "fragment" is intended a portion of the polynucleotide or a portion of the amino acid sequence and hence protein encoded thereby. Fragments of a polynucleotide may encode protein fragments that retain the biological activity of the native protein. Alternatively, fragments of a polynucleotide that are useful as a silencing element do not need to encode fragment proteins that retain biological activity. Thus, fragments of a nucleotide sequence may range from at least about 10, about 15, about 16, about 17, about 18, about 19, nucleotides, about 20 nucleotides, about 22 nucleotides, about 50 nucleotides, about 75 nucleotides, about 100 nucleotides, 200 nucleotides, 300 nucleotides, 400 nucleotides, 500 nucleotides, 600 nucleotides, 700 nucleotides and up to and including one nucleotide less than the full-length polynucleotide employed. Alternatively, fragments of a nucleotide sequence may range from 1 -50, 25-75, 75-125, 50-100, 125-175, 175-225, 100-150, 100-300, 150-200, 200-250, 225-275, 275-325, 250-300, 325-375, 375-425, 300-350, 350-400, 425- 475, 400-450, 475-525, 450-500, 525-575, 575-625, 550-600, 625-675, 675-725, 600-650, 625-675, 675-725, 650-700, 725-825, 825-875, 750-800, 875-925, 925-975, 850-900, 925-975, 975-1025, 950- 1000, 1000-1050, 1025-1075, 1075-1 125, 1050-1 100, 1 125-1 175, 1 100-1200, 1 175-1225, 1225-1275, 1200-1300, 1325-1375, 1375-1425, 1300-1400, 1425-1475, 1475-1525, 1400-1500, 1525-1575, 1575- 1625, 1625-1675, 1675-1725, 1725-1775, 1775-1825, 1825-1875, 1875-1925, 1925-1975, 1975-2025, 2025-2075, 2075-2125, 2125-2175, 2175-2225, 1500-1600, 1600-1700, 1700-1800, 1800-1900, 1900- 2000 of any one of SEQ ID NOS.: 1 -53 or 107-254, or variants and fragments thereof, and complements thereof. Methods to assay for the activity of a desired silencing element are described elsewhere herein.

"Variants" is intended to mean substantially similar sequences. For polynucleotides, a variant comprises a deletion and/or addition of one or more nucleotides at one or more internal sites within the native polynucleotide and/or a substitution of one or more nucleotides at one or more sites in the native polynucleotide. A variant of a polynucleotide that is useful as a silencing element will retain the ability to reduce expression of the target polynucleotide and, in some embodiments, thereby control a plant insect pest of interest. As used herein, a "native" polynucleotide or polypeptide comprises a naturally occurring nucleotide sequence or amino acid sequence, respectively. For polynucleotides, conservative variants include those sequences that, because of the degeneracy of the genetic code, encode the amino acid sequence of one of the disclosed polypeptides. Variant polynucleotides also include synthetically derived polynucleotide, such as those generated, for example, by using site-directed mutagenesis, but continue to retain the desired activity. Generally, variants of a particular disclosed polynucleotide (i.e., a silencing element) will have at least about 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to that particular polynucleotide as determined by sequence alignment programs and parameters described elsewhere herein.

Variants of a particular disclosed polynucleotide (i.e., the reference polynucleotide) can also be evaluated by comparison of the percent sequence identity between the polypeptide encoded by a variant polynucleotide and the polypeptide encoded by the reference polynucleotide. Percent sequence identity between any two polypeptides can be calculated using sequence alignment programs and parameters described elsewhere herein. Where any given pair of disclosed polynucleotides employed is evaluated by comparison of the percent sequence identity shared by the two polypeptides they encode, the percent sequence identity between the two encoded polypeptides is at least about 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity.

The following terms are used to describe the sequence relationships between two or more polynucleotides or polypeptides: (a) "reference sequence", (b) "comparison window", (c) "sequence identity", and, (d) "percentage of sequence identity."

(a) As used herein, "reference sequence" is a defined sequence used as a basis for sequence comparison. A reference sequence may be a subset or the entirety of a specified sequence; for example, as a segment of a full-length cDNA or gene sequence, or the complete cDNA or gene sequence.

(b) As used herein, "comparison window" makes reference to a contiguous and specified segment of a polynucleotide sequence, wherein the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two polynucleotides. Generally, the comparison window is at least 20 contiguous nucleotides in length, and optionally can be 30, 40, 50, 100, or longer. Those of skill in the art understand that to avoid a high similarity to a reference sequence due to inclusion of gaps in the polynucleotide sequence a gap penalty is typically introduced and is subtracted from the number of matches.

Unless otherwise stated, sequence identity/similarity values provided herein refer to the value obtained using GAP Version 10 using the following parameters: % identity and % similarity for a nucleotide sequence using GAP Weight of 50 and Length Weight of 3, and the nwsgapdna.cmp scoring matrix; % identity and % similarity for an amino acid sequence using GAP Weight of 8 and Length Weight of 2, and the BLOSUM62 scoring matrix; or any equivalent program thereof. By "equivalent program" is intended any sequence comparison program that, for any two sequences in question, generates an alignment having identical nucleotide or amino acid residue matches and an identical percent sequence identity when compared to the corresponding alignment generated by GAP Version 10.

(c) As used herein, "sequence identity" or "identity" in the context of two polynucleotides or polypeptide sequences makes reference to the residues in the two sequences that are the same when aligned for maximum correspondence over a specified comparison window. When percentage of sequence identity is used in reference to proteins it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (e.g., charge or hydrophobicity) and therefore do not change the functional properties of the molecule. When sequences differ in conservative substitutions, the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Sequences that differ by such conservative substitutions are said to have "sequence similarity" or "similarity". Means for making this adjustment are well known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch, thereby increasing the percentage sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and 1. The scoring of conservative substitutions is calculated, e.g., as implemented in the program PC/GENE (Intelligenetics, Mountain View, California).

(d) As used herein, "percentage of sequence identity" means the value determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison, and multiplying the result by 100 to yield the percentage of sequence identity.

A method is further provided for identifying a silencing element from the target polynucleotides set forth in SEQ ID NOS.: 1 -53 or 107-254, or variants and fragments thereof, and complements thereof. Such methods comprise obtaining a candidate fragment of any one of SEQ ID NOS. : 1-53 or 107-254, or variants and fragments thereof, and complements thereof, which is of sufficient length to act as a silencing element and thereby reduce the expression of the target polynucleotide and/or control a desired pest; expressing said candidate polynucleotide fragment in an appropriate expression cassette to produce a candidate silencing element and determining is said candidate polynucleotide fragment has the activity of a silencing element and thereby reduce the expression of the target polynucleotide and/or controls a desired pest. Methods of identifying such candidate fragments based on the desired pathway for suppression, in light of the teachings provided herein, are known. For example, various bioinformatics programs can be employed to identify the region of the target polynucleotides that could be exploited to generate a silencing element. See, for example, Elbahir et al. (2001) Genes and Development 15 : 188-200, Schwartz et al. (2003) Cell 1 15 : 199-208, Khvorova et al. (2003) Cell 1 15 :209-216. See also, siRNA at Whitehead (jura.wi.mit.edu/bioc/siPvNAext/) which calculates the binding energies for both sense and antisense siPvNAs. See, also genscript.com/ssl-bin/app/rnai?op=known; Block-iT™ RNAi designer from Invitrogen and GenScript siRNA Construct Builder. In various aspects, it is to be understand that the term " ... SEQ ID NOS. : 1-53 or 107-254, or variants or fragments thereof, or complements thereof... " is intended to mean that the disclosed sequences comprise SEQ ID NOS.: 1-53 or 107-254, and/or fragments of SEQ ID NOS.: 1-53 or 107-254, and/or variants of SEQ ID NOS.: 1-53 or 107-254, and/or the complements of SEQ ID NOS.: 1-53 or 107-254, the variants of SEQ ID NOS.: 1-53 or 107-254, and/or the fragments of SEQ ID NOS.: 1-53 or 107-254, individually (or) or inclusive of some or all listed sequences.

V. DNA constructs

The use of the term "polynucleotide" is not intended to be limiting to polynucleotides comprising DNA. Those of ordinary skill in the art will recognize that polynucleotides can comprise ribonucleotides and combinations of ribonucleotides and deoxyribonucleotides. Such deoxyribonucleotides and ribonucleotides include both naturally occurring molecules and synthetic analogues. The disclosed polynucleotides also encompass all forms of sequences including, but not limited to, single-stranded forms, double-stranded forms, hairpins, stem-and-loop structures, and the like.

The polynucleotide encoding the silencing element or in certain embodiments employed in the disclosed methods and compositions can be provided in expression cassettes for expression in a plant or organism of interest. It is recognized that multiple silencing elements including multiple identical silencing elements, multiple silencing elements targeting different regions of the target sequence, or multiple silencing elements from different target sequences can be used. In this embodiment, it is recognized that each silencing element may be encoded by a single or separate cassette, DNA construct, or vector. As discussed, any means of providing the silencing element is contemplated. A plant or plant cell can be transformed with a single cassette comprising DNA encoding one or more silencing elements or separate cassettes encoding a silencing element can be used to transform a plant or plant cell or host cell. Likewise, a plant transformed with one component can be subsequently transformed with the second component. One or more DNA constructs encoding silencing elements can also be brought together by sexual crossing. That is, a first plant comprising one component is crossed with a second plant comprising the second component. Progeny plants from the cross will comprise both components.

The expression cassette can include 5' and 3' regulatory sequences operably linked to the polynucleotide of the invention. "Operably linked" is intended to mean a functional linkage between two or more elements. For example, an operable linkage between a polynucleotide of the invention and a regulatory sequence (i.e., a promoter) is a functional link that allows for expression of the polynucleotide disclosed herein. Operably linked elements may be contiguous or non-contiguous. When used to refer to the joining of two protein coding regions, by operably linked is intended that the coding regions are in the same reading frame. The cassette may additionally contain at least one additional polynucleotide to be cotransformed into the organism. Alternatively, the additional polypeptide(s) can be provided on multiple expression cassettes. Expression cassettes can be provided with a plurality of restriction sites and/or recombination sites for insertion of the polynucleotide to be under the transcriptional regulation of the regulatory regions. The expression cassette may additionally contain selectable marker genes.

The expression cassette can include in the 5'-3' direction of transcription, a transcriptional and translational initiation region (i.e., a promoter), a polynucleotide encoding the silencing element employed in the methods and compositions of the invention, and a transcriptional and translational termination region (i.e., termination region) functional in plants. In other embodiment, the double stranded RNA is expressed from a suppression cassette. Such a cassette can comprise two convergent promoters that drive transcription of an operably linked silencing element. "Convergent promoters" refers to promoters that are oriented on either terminus of the operably linked polynucleotide encoding the silencing element such that each promoter drives transcription of the silencing element in opposite directions, yielding two transcripts. In such embodiments, the convergent promoters allow for the transcription of the sense and anti-sense strand and thus allow for the formation of a dsRNA. Such a cassette may also comprise two divergent promoters that drive transcription of one or more operably linked polynucleotides encoding the silencing elements. "Divergent promoters" refers to promoters that are oriented in opposite directions of each other, driving transcription of the one or more polynucleotides encoding the silencing elements in opposite directions. In such embodiments, the divergent promoters allow for the transcription of the sense and antisense strands and allow for the formation of a dsRNA. In such embodiments, the divergent promoters also allow for the transcription of at least two separate hairpin RNAs. In another embodiment, one cassette comprising two or more polynucleotides encoding the silencing elements under the control of two separate promoters in the same orientation is present in a construct. In another embodiment, two or more individual cassettes, each comprising at least one polynucleotide encoding the silencing element under the control of a promoter, are present in a construct in the same orientation.

The regulatory regions (i.e., promoters, transcriptional regulatory regions, and translational termination regions) and/or the polynucleotides disclosed herein may be native/analogous to the host cell or to each other. Alternatively, the regulatory regions and/or the polynucleotide disclosed herein may be heterologous to the host cell or to each other. As used herein, "heterologous" in reference to a sequence is a sequence that originates from a foreign species, or, if from the same species, is substantially modified from its native form in composition and/or genomic locus by deliberate human intervention. For example, a promoter operably linked to a heterologous polynucleotide is from a species different from the species from which the polynucleotide was derived, or, if from the same/analogous species, one or both are substantially modified from their original form and/or genomic locus, or the promoter is not the native promoter for the operably linked polynucleotide. As used herein, a chimeric gene comprises a coding sequence operably linked to a transcription initiation region that is heterologous to the coding sequence.

The termination region may be native with the transcriptional initiation region, may be native with the operably linked polynucleotide encoding the silencing element, may be native with the plant host, or may be derived from another source (i.e., foreign or heterologous) to the promoter, the polynucleotide encoding the silencing element, the plant host, or any combination thereof. Convenient termination regions are available from the Ti-plasmid of A. tumefaciens , such as the octopine synthase and nopaline synthase termination regions. See also Guerineau et al. ( 1991) Mol. Gen. Genet. 262: 141-144; Proudfoot ( 1991) Cell 64:671-674; Sanfacon et al. (1991) Genes Dev. 5 : 141-149; Mogen et al. (1990) Plant Cell 2: 1261-1272; Munroe et al. (1990) Gene 91 : 151-158; Ballas et al. ( 1989) Nucleic Acids Res. 17:7891-7903; and Joshi et al. (1987) Nucleic Acids Res. 15 :9627-9639.

Additional sequence modifications are known to enhance gene expression in a cellular host. These include elimination of sequences encoding spurious polyadenylation signals, exon-intron splice site signals, transposon-like repeats, and other such well-characterized sequences that may be deleterious to gene expression. The G-C content of the sequence may be adjusted to levels average for a given cellular host, as calculated by reference to known genes expressed in the host cell. When possible, the sequence is modified to avoid predicted hairpin secondary mRNA structures.

In preparing the expression cassette, the various DNA fragments may be manipulated, so as to provide for the DNA sequences in the proper orientation and, as appropriate, in the proper reading frame. Toward this end, adapters or linkers may be employed to join the DNA fragments or other manipulations may be involved to provide for convenient restriction sites, removal of superfluous DNA, removal of restriction sites, or the like. For this purpose, in vitro mutagenesis, primer repair, restriction, annealing, resubstitutions, e.g., transitions and transversions, may be involved.

A number of promoters can be used in the practice of the invention. The promoters can be selected based on the desired outcome. The nucleic acids can be combined with constitutive, tissue- preferred, inducible, or other promoters for expression in the host organism.

Such constitutive promoters include, for example, the core promoter of the Rsyn7 promoter and other constitutive promoters disclosed in WO 99/43838 and U.S. Patent No. 6,072,050; the core CaMV 35S promoter (Odell et al. ( 1985) Nature 313 : 810-812); rice actin (McElroy et al. (1990) Plant Cell 2: 163-171); ubiquitin (Christensen et al. (1989) Plant Mol. Biol. 12:619-632 and Christensen et al. (1992) Plant Mol. Biol. 18: 675-689); pEMU (Last et al. (1991) Theor. Appl. Genet. 81 :581-588); MAS (Velten et al. ( 1984) EMBO J. 3 :2723-2730); ALS promoter (U.S. Patent No. 5,659,026), and the like. Other constitutive promoters include, for example, U.S. Patent Nos. 5,608, 149; 5,608, 144; 5,604, 121 ; 5,569,597; 5,466,785; 5,399,680; 5,268,463; 5,608, 142; and 6, 177,61 1.

Depending on the desired outcome, it may be beneficial to express the gene from an inducible promoter. An inducible promoter, for instance, a pathogen-inducible promoter could also be employed. Such promoters include those from pathogenesis-related proteins (PR proteins), which are induced following infection by a pathogen; e.g., PR proteins, SAR proteins, beta-l,3-glucanase, chitinase, etc. See, for example, Redolfi et al. (1983) Neth. J. Plant Pathol. 89:245-254; Uknes et al. ( 1992) Plant Cell 4:645-656; and Van Loon (1985) Plant Mol. Virol. 4: 11 1-1 16. See also WO 99/43819.

Additionally, as pathogens find entry into plants through wounds or insect damage, a wound- inducible promoter may be used in the constructions of the invention. Such wound-inducible promoters include potato proteinase inhibitor (pin II) gene (Ryan ( 1990) Ann. Rev. Phytopath. 28:425- 449; Duan et al. (1996) Nature Biotechnology 14:494-498); wunl and wun2, U.S. Patent No. 5,428, 148; winl and win2 (Stanford et al. (1989) Mol. Gen. Genet. 215 :200-208); systemin (McGurl et al. (1992) Science 225: 1570-1573); WIP 1 (Rohmeier et al. (1993) Plant Mol. Biol. 22: 783-792; Eckelkamp et al. (1993) FEBS Letters 323 :73-76); MPI gene (Corderok et al. (1994) Plant J. 6(2): 141-150); and the like,.

Additionally, pathogen-inducible promoters may be employed in the methods and nucleotide constructs of the embodiments. Such pathogen-inducible promoters include those from pathogenesis- related proteins (PR proteins), which are induced following infection by a pathogen; e.g., PR proteins, SAR proteins, beta-l,3-glucanase, chitinase, etc. See, for example, Redolfi et al. (1983) Neth. J. Plant Pathol. 89: 245-254; Uknes et al. ( 1992) Plant Cell 4: 645-656; and Van Loon ( 1985) Plant Mol. Virol. 4: 1 1 1-1 16. See also WO 99/43819.

Of interest are promoters that are expressed locally at or near the site of pathogen infection. See, for example, Marineau et al. (1987) Plant Mol. Biol. 9:335-342; Matton et al. (1989) Molecular Plant-Microbe Interactions 2:325-331 ; Somsisch et al. ( 1986) Proc. Natl. Acad. Sci. USA 83 :2427- 2430; Somsisch et al. (1988) Mol. Gen. Genet. 2:93-98; and Yang (1996) Proc. Natl. Acad. Sci. USA 93 : 14972-14977. See also, Chen et al. (1996) Plant J. 10:955-966; Zhang et al. (1994) Proc. Natl. Acad. Sci. USA 91 :2507-251 1 ; Warner et al. (1993) Plant J. 3 : 191-201 ; Siebertz et al. ( 1989) Plant Cell 1 :961-968; U.S. Patent No. 5,750,386 (nematode -inducible). Of particular interest is the inducible promoter for the maize PRms gene, whose expression is induced by the pathogen Fusarium moniliforme (see, for example, Cordero et al. ( 1992) Physiol. Mol. Plant Path. 41 : 189-200).

Chemical -regulated promoters can be used to modulate the expression of a gene in a plant through the application of an exogenous chemical regulator. Depending upon the objective, the promoter may be a chemical-inducible promoter, where application of the chemical induces gene expression, or a chemical-repressible promoter, where application of the chemical represses gene expression. Chemical-inducible promoters are known in the art and include, but are not limited to, the maize In2-2 promoter, which is activated by benzenesulfonamide herbicide safeners, the maize GST promoter, which is activated by hydrophobic electrophilic compounds that are used as pre-emergent herbicides, and the tobacco PR-la promoter, which is activated by salicylic acid. Other chemical- regulated promoters of interest include steroid-responsive promoters (see, for example, the glucocorticoid-inducible promoter in Schena et al. (1991) Proc. Natl. Acad. Sci. USA 88: 10421-10425 and McNellis et al. (1998) Plant J. 14(2):247-257) and tetracycline-inducible and tetracycline- repressible promoters (see, for example, Gatz et al. (1991) Mol. Gen. Genet. 227:229-237, and U.S. Patent Nos. 5,814,618 and 5,789, 156).

Tissue-preferred promoters can be utilized to target enhanced expression within a particular plant tissue. Tissue-preferred promoters include Yamamoto et al. ( 1997) Plant J. 12(2):255-265; Kawamata et al. (1997) Plant Cell Physiol. 38(7):792-803; Hansen et al. (1997) Mol. Gen Genet. 254(3):337-343; Russell et al. ( 1997) Transgenic Res. 6(2): 157-168; Rinehart et al. (1996) Plant Physiol. 112(3): 1331-1341 ; Van Camp et al. (1996) Plant Physiol. 1 12(2):525-535; Canevascini et al. ( 1996) Plant Physiol. 1 12(2):513-524; Yamamoto et al. (1994) Plant Cell Physiol. 35(5):773-778; Lam ( 1994) Results Probl. Cell Differ. 20: 181-196; Orozco et al. (1993) Plant Mol Biol. 23(6): 1 129- 1 138; Matsuoka et al. ( 1993) Proc Natl. Acad. Sci. USA 90(20):9586-9590; and Guevara-Garcia et al. (1993) Plant J. 4(3):495-505. Such promoters can be modified, if necessary, for weak expression.

Leaf-preferred promoters are known in the art. See, for example, Yamamoto et al. (1997) Plant J. 12(2):255-265; Kwon et al. ( 1994) Plant Physiol. 105 :357-67; Yamamoto et al. (1994) Plant Cell Physiol. 35(5):773-778; Gotor et al. ( 1993) Plant J. 3 :509-18; Orozco et al. ( 1993) Plant Mol. Biol. 23(6): 1 129-1 138; and Matsuoka et al. ( 1993) Proc. Natl. Acad. Sci. USA 90(20):9586-9590.

Root-preferred promoters are known and can be selected from the many available from the literature or isolated de novo from various compatible species. See, for example, Hire et al. ( 1992) Plant Mol. Biol. 20(2):207-218 (soybean root-specific glutamine synthetase gene); Keller and Baumgartner ( 1991) Plant Cell 3( 10): 1051-1061 (root-specific control element in the GRP 1.8 gene of French bean); Sanger et al. ( 1990) Plant Mol. Biol. 14(3):433-443 (root-specific promoter of the mannopine synthase (MAS) gene of Agrobacterium tumefaciens); and Miao et al. (1991) Plant Cell 3(1): 11-22 (full-length cDNA clone encoding cytosolic glutamine synthetase (GS), which is expressed in roots and root nodules of soybean). See also Bogusz et al. ( 1990) Plant Cell 2(7) : 633 - 641, where two root-specific promoters isolated from hemoglobin genes from the nitrogen-fixing nonlegume Parasponia andersonii and the related non-nitrogen-fixing nonlegume Trema tomentosa are described. The promoters of these genes were linked to a β-glucuronidase reporter gene and introduced into both the nonlegume Nicotiana tabacum and the legume Lotus corniculatus , and in both instances root-specific promoter activity was preserved. Leach and Aoyagi (1991) describe their analysis of the promoters of the highly expressed rolC and rolD root-inducing genes of Agrobacterium rhizogenes (see Plant Science (Limerick) 79( 1): 69-76). They concluded that enhancer and tissue-preferred DNA determinants are dissociated in those promoters. Teeri et al. (1989) used gene fusion to lacZ to show that the Agrobacterium T-DNA gene encoding octopine synthase is especially active in the epidermis of the root tip and that the TR2' gene is root specific in the intact plant and stimulated by wounding in leaf tissue, an especially desirable combination of characteristics for use with an insecticidal or larvicidal gene (see EMBO J. 8(2):343-350). The TR1' gene, fused to nptll (neomycin phosphotransferase II) showed similar characteristics. Additional root-preferred promoters include the VfENOD-GRP3 gene promoter (Kuster et al. ( 1995) Plant Mol. Biol. 29(4):759-772); and rolB promoter (Capana et al. (1994) Plant Mol. Biol. 25(4):681-691. See also U.S. Patent Nos. 5,837,876; 5,750,386; 5,633,363; 5,459,252; 5,401,836; 5, 1 10,732; and 5,023, 179.

Seed-preferred" promoters include both "seed-specific" promoters (those promoters active during seed development such as promoters of seed storage proteins) as well as "seed-germinating" promoters (those promoters active during seed germination). See Thompson et al. ( 1989) BioEssays 10: 108. Such seed-preferred promoters include, but are not limited to, Ciml (cytokinin-induced message); cZ19B l (maize 19 kDa zein); and milps (myo-inositol-1 -phosphate synthase) (see U.S. Patent No. 6,225,529, herein incorporated by reference). Gamma-zein and Glob-1 are endosperm- specific promoters. For dicots, seed-specific promoters include, but are not limited to, bean □- phaseolin, nap in,□ -conglycinin, soybean lectin, cruciferin, and the like. For monocots, seed-specific promoters include, but are not limited to, maize 15 kDa zein, 22 kDa zein, 27 kDa zein, g-zein, waxy, shrunken 1, shrunken 2, globulin 1, etc. See also WO 00/12733, where seed-preferred promoters from endl and end2 genes are disclosed. A promoter that has "preferred" expression in a particular tissue is expressed in that tissue to a greater degree than in at least one other plant tissue. Some tissue-preferred promoters show expression almost exclusively in the particular tissue.

In an embodiment, the plant-expressed promoter is a vascular-specific promoter such as a phloem-specific promoter. A "vascular-specific" promoter, as used herein, is a promoter which is at least expressed in vascular cells, or a promoter which is preferentially expressed in vascular cells. Expression of a vascular-specific promoter need not be exclusively in vascular cells, expression in other cell types or tissues is possible. A "phloem-specific promoter" as used herein, is a plant- expressible promoter which is at least expressed in phloem cells, or a promoter which is preferentially expressed in phloem cells.

Expression of a phloem-specific promoter need not be exclusively in phloem cells, expression in other cell types or tissues, e.g., xylem tissue, is possible. In one embodiment of this invention, a phloem-specific promoter is a plant-expressible promoter at least expressed in phloem cells, wherein the expression in non-phloem cells is more limited (or absent) compared to the expression in phloem cells. Examples of suitable vascular-specific or phloem -specific promoters in accordance with this invention include but are not limited to the promoters selected from the group consisting of: the SCSV3, SCSV4, SCSV5, and SCSV7 promoters (Schunmann et al.

Where low level expression is desired, weak promoters will be used. Generally, the term "weak promoter" as used herein refers to a promoter that drives expression of a coding sequence at a low level. By low level expression at levels of about 1/1000 transcripts to about 1/100,000 transcripts to about 1/500,000 transcripts is intended. Alternatively, it is recognized that the term "weak promoters" also encompasses promoters that drive expression in only a few cells and not in others to give a total low level of expression. Where a promoter drives expression at unacceptably high levels, portions of the promoter sequence can be deleted or modified to decrease expression levels.

Such weak constitutive promoters include, for example the core promoter of the Rsyn7 promoter (WO 99/43838 and U.S. Patent No. 6,072,050), the core 35S CaMV promoter, and the like. Other constitutive promoters include, for example, those disclosed in U.S. Patent Nos. 5,608, 149; 5,608, 144; 5,604, 121 ; 5,569,597; 5,466,785; 5,399,680; 5,268,463; 5,608, 142; and 6, 177,611.

The expression cassette can also comprise a selectable marker gene for the selection of transformed cells. Selectable marker genes are utilized for the selection of transformed cells or tissues. Marker genes include genes encoding antibiotic resistance, such as those encoding neomycin phosphotransferase II (NEO) and hygromycin phosphotransferase (HPT), as well as genes conferring resistance to herbicidal compounds, such as glufosinate ammonium, bromoxynil, imidazolinones, and 2,4-dichlorophenoxyacetate (2,4-D). Additional selectable markers include phenotypic markers such as β-galactosidase and fluorescent proteins such as green fluorescent protein (GFP) (Su et al. (2004) Biotechnol Bioeng 55:610-9 and Fetter et al. (2004) Plant Cell 7 (5:215-28), cyan florescent protein (CYP) (Bolte et al. (2004) J. Cell Science 777:943-54 and Kato et al. (2002) Plant Physiol 729:913- 42), and yellow florescent protein (PhiYFP™ from Evrogen, see, Bolte et al. (2004) J. Cell Science 777:943-54).

VI. Compositions Comprising Silencing Elements

One or more of the polynucleotides comprising the silencing element may be provided as an external composition such as a spray or powder to the plant, plant part, seed, a plant insect pest, or an area of cultivation. In another example, a plant is transformed with a DNA construct or expression cassette for expression of at least one silencing element. In either composition, the silencing element, when ingested by an insect, can reduce the level of a target pest sequence and thereby control the pest (i.e., a Coleopteran plant pest including a Diabrotica plant pest, such as, D. virgifera virgifera, D. barberi, D. virgifera zeae, D. speciosa, or D. undecimpunctata howardi). It is recognized that the composition may comprise a cell (such as plant cell or a bacterial cell), in which a polynucleotide encoding the silencing element is stably incorporated into the genome and operably linked to promoters active in the cell. Compositions comprising a mixture of cells, some cells expressing at least one silencing element are also encompassed. In other embodiments, compositions comprising the silencing elements are not contained in a cell. In such embodiments, the composition can be applied to an area inhabited by a plant insect pest. In one embodiment, the composition is applied externally to a plant (i.e., by spraying a field or area of cultivation) to protect the plant from the pest. Methods of applying nucleotides in such a manner are known to those of skill in the art.

A composition disclosed herein may further be formulated as bait. In this embodiment, the compositions comprise a food substance or an attractant which enhances the attractiveness of the composition to the pest.

A composition comprising the silencing element may be formulated in an agriculturally suitable and/or environmentally acceptable carrier. Such carriers may be any material that the animal, plant or environment to be treated can tolerate. Furthermore, the carrier must be such that the composition remains effective at controlling a plant insect pest. Examples of such carriers include water, saline, Ringer's solution, dextrose or other sugar solutions, Hank's solution, and other aqueous physiologically balanced salt solutions, phosphate buffer, bicarbonate buffer and Tris buffer. In addition, the composition may include compounds that increase the half-life of a composition. Various insecticidal formulations can also be found in, for example, US Publications 2008/0275115, 2008/0242174, 2008/0027143, 2005/0042245, and 2004/0127520.

It is recognized that the polynucleotides comprising sequences encoding the silencing element may be used to transform organisms to provide for host organism production of these components, and subsequent application of the host organism to the environment of the target pest(s). Such host organisms include baculoviruses, bacteria, and the like. In this manner, the combination of polynucleotides encoding the silencing element may be introduced via a suitable vector into a microbial host, and said host applied to the environment, or to plants or animals.

The term "introduced" in the context of inserting a nucleic acid into a cell, means "transfection" or "transformation" or "transduction" and includes reference to the incorporation of a nucleic acid into a eukaryotic or prokaryotic cell where the nucleic acid may be stably incorporated into the genome of the cell (e.g., chromosome, plasmid, plastid, or mitochondrial DNA), converted into an autonomous replicon, or transiently expressed (e.g., transfected mRNA).

Microbial hosts that are known to occupy the "phytosphere" (phylloplane, phyllosphere, rhizosphere, and/or rhizoplana) of one or more crops of interest may be selected. These microorganisms are selected so as to be capable of successfully competing in the particular environment with the wild-type microorganisms, provide for stable maintenance and expression of the sequences encoding the silencing element, and desirably, provide for improved protection of the components from environmental degradation and inactivation.

Such microorganisms include bacteria, algae, and fungi. Of particular interest are microorganisms such as bacteria, e.g., Pseudomonas, Erwinia, Serratia, Klebsiella, Xanthomonas, Streptomyces, Rhizobium, Rhodopseudomonas, Methylius, Agrobacterium, Acetobacter, Lactobacillus, Arthrobacter, Azotobacter, Leuconostoc, and Alcaligenes, fungi, particularly yeast, e.g., Saccharomyces, Cryptococcus, Kluyveromyces, Sporobolomyces, Rhodotorula, and Aureobasidium. Of particular interest are such phytosphere bacterial species as Pseudomonas syringae, Pseudomonas fluorescens, Serratia marcescens, Acetobacter xylinum, Agrobacteria, Rhodopseudomonas spheroides, Xanthomonas campestris, Rhizobium melioti, Alcaligenes entrophus, Clavibacter xyli and Azotobacter vinlandir, and phytosphere yeast species such as Rhodotorula rubra, R. glutinis, R. marina, R. aurantiaca, Cryptococcus albidus, C. diffluens, C. laurentii, Saccharomyces rosei, S. pretoriensis, S. cerevisiae, Sporobolomyces rosues, S. odorus, Kluyveromyces veronae, and Aureobasidium pollulans. Of particular interest are the pigmented microorganisms.

A number of ways are available for introducing the polynucleotide comprising the silencing element into the microbial host under conditions that allow for stable maintenance and expression of such nucleotide encoding sequences. For example, expression cassettes can be constructed which include the nucleotide constructs of interest operably linked with the transcriptional and translational regulatory signals for expression of the nucleotide constructs, and a nucleotide sequence homologous with a sequence in the host organism, whereby integration will occur, and/or a replication system that is functional in the host, whereby integration or stable maintenance will occur.

Transcriptional and translational regulatory signals include, but are not limited to, promoters, transcriptional initiation start sites, operators, activators, enhancers, other regulatory elements, ribosomal binding sites, an initiation codon, termination signals, and the like. See, for example, U.S. Patent Nos. 5,039,523 and 4,853,331; EP 0480762A2; Sambrook et al. (2000); Molecular Cloning: A Laboratory Manual (3^rd edition; Cold Spring Harbor Laboratory Press, Plainview, NY); Davis et al. (1980) Advanced Bacterial Genetics (Cold Spring Harbor Laboratory, Cold Spring Harbor, NY); and the references cited therein.

Suitable host cells include the prokaryotes and the lower eukaryotes, such as fungi. Illustrative prokaryotes, both Gram-negative and Gram-positive, include Enterobacteriaceae , such as Escherichia, Erwinia, Shigella, Salmonella, and Proteus; Bacillaceae; Rhizobiceae, such as Rhizobium; Spirillaceae, such as photobacterium, Zymomonas , Serratia, Aeromonas, Vibrio, Desulfovibrio, Spirillum; Lactobacillaceae; Pseudomonadaceae, such as Pseudomonas and Acetobacter; Azotobacteraceae and Nitrobacteraceae. Among eukaryotes are fungi, such as Phycomycetes and Ascomycetes, which includes yeast, such as Saccharomyces and Schizosaccharomyces; and Basidiomycetes yeast, such as Rhodotorula, Aureobasidium, Sporobolomyces , and the like.

Characteristics of particular interest in selecting a host cell may include ease of introducing the coding sequence into the host, availability of expression systems, efficiency of expression, stability in the host, and the presence of auxiliary genetic capabilities. Characteristics of interest for use as a pesticide microcapsule include protective qualities, such as thick cell walls, pigmentation, and intracellular packaging or formation of inclusion bodies; leaf affinity; lack of mammalian toxicity; attractiveness to pests for ingestion; and the like. Other considerations include ease of formulation and handling, economics, storage stability, and the like.

Host organisms of particular interest include yeast, such as Rhodotorula spp., Aureobasidium spp. , Saccharomyces spp. , and Sporobolomyces spp. , phylloplane organisms such as Pseudomonas spp., Erwinia spp., and Flavobacterium spp., and other such organisms, including Pseudomonas aeruginosa, Pseudomonas fluorescens, Saccharomyces cerevisiae, Bacillus thuringiensis, Escherichia coli, Bacillus subtilis, and the like.

The sequences encoding the silencing elements encompassed by the invention may be introduced into microorganisms that multiply on plants (epiphytes) to deliver these components to potential target pests. Epiphytes, for example, can be gram-positive or gram-negative bacteria.

A silencing element may be fermented in a bacterial host and the resulting bacteria processed and used as a microbial spray in the same manner that Bacillus thuringiensis strains have been used as insecticidal sprays. Any suitable microorganism can be used for this purpose. By way of example, Pseudomonas has been used to express Bacillus thuringiensis endotoxins as encapsulated proteins and the resulting cells processed and sprayed as an insecticide Gaertner et al. (1993), in Advanced Engineered Pesticides, ed. L. Kim (Marcel Decker, Inc.).

Alternatively, the components of the invention are produced by introducing heterologous genes into a cellular host. Expression of the heterologous sequences results, directly or indirectly, in the intracellular production of a silencing element. These compositions may then be formulated in accordance with conventional techniques for application to the environment hosting a target pest, e.g., soil, water, and foliage of plants. See, for example, EPA 0192319, and the references cited therein.

A transformed microorganism can be formulated with an acceptable carrier into separate or combined compositions that are, for example, a suspension, a solution, an emulsion, a dusting powder, a dispersible granule, a wettable powder, and an emulsifiable concentrate, an aerosol, an impregnated granule, an adjuvant, a coatable paste, and also encapsulations in, for example, polymer substances.

Such compositions disclosed above may be obtained by the addition of a surface-active agent, an inert carrier, a preservative, a humectant, a feeding stimulant, an attractant, an encapsulating agent, a binder, an emulsifier, a dye, a UV protectant, a buffer, a flow agent or fertilizers, micronutrient donors, or other preparations that influence plant growth. One or more agrochemicals including, but not limited to, herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides, acaracides, plant growth regulators, harvest aids, and fertilizers, can be combined with carriers, surfactants or adjuvants customarily employed in the art of formulation or other components to facilitate product handling and application for particular target pests. Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g., natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, binders, or fertilizers. The active ingredients (i.e., at least one silencing element) are normally applied in the form of compositions and can be applied to the crop area, plant, or seed to be treated. For example, the compositions may be applied to grain in preparation for or during storage in a grain bin or silo, etc. The compositions may be applied simultaneously or in succession with other compounds. Methods of applying an active ingredient or a composition that contains at least one silencing element include, but are not limited to, foliar application, seed coating, and soil application. The number of applications and the rate of application depend on the intensity of infestation by the corresponding pest.

Suitable surface-active agents include, but are not limited to, anionic compounds such as a carboxylate of, for example, a metal; carboxylate of a long chain fatty acid; an N-acylsarcosinate; mono- or di-esters of phosphoric acid with fatty alcohol ethoxylates or salts of such esters; fatty alcohol sulfates such as sodium dodecyl sulfate, sodium octadecyl sulfate, or sodium cetyl sulfate; ethoxylated fatty alcohol sulfates; ethoxylated alkylphenol sulfates; lignin sulfonates; petroleum sulfonates; alkyl aryl sulfonates such as alkyl-benzene sulfonates or lower alkylnaphtalene sulfonates, e.g., butyl-naphthalene sulfonate; salts of sulfonated naphthalene -formaldehyde condensates; salts of sulfonated phenol-formaldehyde condensates; more complex sulfonates such as the amide sulfonates, e.g., the sulfonated condensation product of oleic acid and N-methyl taurine; or the dialkyl sulfosuccinates, e.g., the sodium sulfonate or dioctyl succinate. Non-ionic agents include condensation products of fatty acid esters, fatty alcohols, fatty acid amides or fatty-alkyl- or alkenyl- substituted phenols with ethylene oxide, fatty esters of polyhydric alcohol ethers, e.g., sorbitan fatty acid esters, condensation products of such esters with ethylene oxide, e.g., polyoxyethylene sorbitan fatty acid esters, block copolymers of ethylene oxide and propylene oxide, acetylenic glycols such as 2,4,7,9-tetraethyl-5-decyn-4,7-diol, or ethoxylated acetylenic glycols. Examples of a cationic surface- active agent include, for instance, an aliphatic mono-, di-, or polyamine such as an acetate, naphthenate or oleate; or oxygen-containing amine such as an amine oxide of polyoxyethylene alkylamine; an amide-linked amine prepared by the condensation of a carboxylic acid with a di- or polyamine; or a quaternary ammonium salt. Examples of inert materials include, but are not limited to, inorganic minerals such as kaolin, phyllosilicates, carbonates, sulfates, phosphates, or botanical materials such as cork, powdered corncobs, peanut hulls, rice hulls, and walnut shells.

The compositions comprising a silencing element may be in a suitable form for direct application or as a concentrate of primary composition that requires dilution with a suitable quantity of water or other dilutant before application.

The compositions (including the transformed microorganisms) may be applied to the environment of an insect pest (such as a Coleoptera plant pest or a Diabrotica plant pest) by, for example, spraying, atomizing, dusting, scattering, coating or pouring, introducing into or on the soil, introducing into irrigation water, by seed treatment or general application or dusting at the time when the pest has begun to appear or before the appearance of pests as a protective measure. For example, the composition(s) and/or transformed microorganism(s) may be mixed with grain to protect the grain during storage. It is generally important to obtain good control of pests in the early stages of plant growth, as this is the time when the plant can be most severely damaged. The compositions can conveniently contain another insecticide if this is thought necessary. In an embodiment of the invention, the composition(s) is applied directly to the soil, at a time of planting, in granular form of a composition of a carrier and dead cells of a Bacillus strain or transformed microorganism of the invention. Another embodiment is a granular form of a composition comprising an agrochemical such as, for example, an herbicide, an insecticide, a fertilizer, in an inert carrier, and dead cells of a Bacillus strain or transformed microorganism of the invention.

VII. Plants, Plant Parts, and Methods of Introducing Sequences into Plants

In one embodiment, the methods of the invention involve introducing a polynucleotide into a plant. "Introducing" is intended to mean presenting to the plant the polynucleotide in such a manner that the sequence gains access to the interior of a cell of the plant. The methods of the invention do not depend on a particular method for introducing a sequence into a plant, only that the polynucleotide or polypeptides gains access to the interior of at least one cell of the plant. Methods for introducing polynucleotides into plants are known in the art including, but not limited to, stable transformation methods, transient transformation methods, and virus-mediated methods.

"Stable transformation" is intended to mean that the nucleotide construct introduced into a plant integrates into the genome of the plant and is capable of being inherited by the progeny thereof.

"Transient transformation" is intended to mean that a polynucleotide is introduced into the plant and does not integrate into the genome of the plant or a polypeptide is introduced into a plant.

Transformation protocols as well as protocols for introducing polypeptides or polynucleotide sequences into plants may vary depending on the type of plant or plant cell, i.e., monocot or dicot, targeted for transformation. Suitable methods of introducing polypeptides and polynucleotides into plant cells include microinjection (Crossway et al. (1986) Biotechniques 4:320-334), electroporation (Riggs et al. (1986) Proc. Natl. Acad. Sci. USA 83 :5602-5606, Agrobacterium- ediated transformation (U.S. Patent No. 5,563,055 and U.S. Patent No. 5,981,840), direct gene transfer (Paszkowski et al. (1984) EMBO J. 3 :2717-2722), and ballistic particle acceleration (see, for example, U.S. Patent Nos. 4,945,050; U.S. Patent No. 5,879,918; U.S. Patent No. 5,886,244; and, 5,932,782; Tomes et al.

(1996) Nature Biotechnology 14:745-750 (maize via Agrobacterium tumefaciens) .

In certain embodiments, a silencing element disclosed herein may be provided to a plant using a variety of transient transformation methods. Such transient transformation methods include, but are not limited to, the introduction of the protein or variants or fragments thereof directly into the plant or the introduction of the transcript into the plant. Such methods include, for example, microinjection or particle bombardment. See, for example, Crossway et al. ( 1986) Mol Gen. Genet. 202: 179-185; Nomura et al. (1986) Plant Sci. 44:53-58; Hepler et al. (1994) Proc. Natl. Acad. Sci. 91 : 2176-2180 and Hush et al. ( 1994) The Journal of Cell Science 107:775-784, all of which are herein incorporated by reference. Alternatively, polynucleotides can be transiently transformed into the plant using techniques known in the art. Such techniques include viral vector systems and the precipitation of the polynucleotide in a manner that precludes subsequent release of the DNA. Such methods include the use of particles coated with polyethylimine (PEI; Sigma #P3143).

In other embodiments, the polynucleotides disclosed herien may be introduced into plants by contacting plants with a virus or viral nucleic acids. Generally, such methods involve incorporating a nucleotide construct of the invention within a viral DNA or RNA molecule. Further, it is recognized that promoters may also encompass promoters utilized for transcription by viral RNA polymerases. Methods for introducing polynucleotides into plants and expressing a protein encoded therein, involving viral DNA or RNA molecules, are known in the art. See, for example, U.S. Patent Nos. 5,889, 191, 5,889, 190, 5,866,785, 5,589,367, 5,316,931, and Porta et al. (1996) Molecular Biotechnology 5:209-221.

Methods are known in the art for the targeted insertion of a polynucleotide at a specific location in the plant genome. In one embodiment, the insertion of the polynucleotide at a desired genomic location is achieved using a site-specific recombination system. See, for example, W099/25821, W099/25854, WO99/25840, W099/25855, and W099/25853. Briefly, the polynucleotides disclosed hereinmay be contained in transfer cassette flanked by two non- recombinogenic recombination sites. The transfer cassette is introduced into a plant having stably incorporated into its genome a target site which is flanked by two non-recombinogenic recombination sites that correspond to the sites of the transfer cassette. An appropriate recombinase is provided and the transfer cassette is integrated at the target site. The polynucleotide of interest is thereby integrated at a specific chromosomal position in the plant genome.

The cells that have been transformed may be grown into plants in accordance with conventional ways. See, for example, McCormick et al. (1986) Plant Cell Reports 5 : 81-84. These plants may then be grown, and either pollinated with the same transformed strain or different strains, and the resulting progeny having constitutive expression of the desired phenotypic characteristic identified. Two or more generations may be grown to ensure that expression of the desired phenotypic characteristic is stably maintained and inherited and then seeds harvested to ensure expression of the desired phenotypic characteristic has been achieved. In this manner, the compositions and methods described herein provide transformed seeds (also referred to as "transgenic seed") having a polynucleotide disclosed herein, for example, an expression cassette, stably incorporated into their genome.

As used herein, the term plant includes plant cells, plant protoplasts, plant cell tissue cultures from which plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants such as embryos, pollen, ovules, seeds, leaves, flowers, branches, fruit, kernels, ears, cobs, husks, stalks, roots, root tips, anthers, and the like. Grain is intended to mean the mature seed produced by commercial growers for purposes other than growing or reproducing the species. Progeny, variants, and mutants of the regenerated plants are also included within the scope of the invention, provided that these parts comprise the introduced polynucleotides.

The compositions and methods described herein may be used for transformation of any plant species, including, but not limited to, monocots and dicots.

Vegetables include tomatoes (Lycopersicon esculentum), lettuce (e.g., Lactuca sativd), green beans (Phaseolus vulgaris), lima beans (Phaseolus limensis), peas (Lathyrus spp.), and members of the genus Cucumis such as cucumber (C. sativus), cantaloupe (C. cantalupensis), and musk melon (C. melo). Ornamentals include azalea (Rhododendron spp.), hydrangea (Macrophylla hydrangea), hibiscus (Hibiscus rosasanensis), roses (Rosa spp.), tulips (Tulipa spp.), daffodils (Narcissus spp.), petunias (Petunia hybrida), carnation (Dianthus caryophyllus), poinsettia (Euphorbia pulcherrima), and chrysanthemum.

Conifers that may be employed in practicing the compositions and methods described herein include, for example, pines such as loblolly pine (Pinus taeda), slash pine (Pinus elliotii), ponderosa pine (Pinus ponderosa), lodgepole pine (Pinus contorta), and Monterey pine (Pinus radiata); Douglas-fir (Pseudotsuga menziesii); Western hemlock (Tsuga canadensis); Sitka spruce (Picea glauca); redwood (Sequoia sempervirens); true firs such as silver fir (Abies amabilis) and balsam fir (Abies balsamea); and cedars such as Western red cedar (Thuja plicata) and Alaska yellow-cedar (Chamaecyparis nootkatensis). In certain embodiments, the compositions and methods described herein can be used with plants such as crop plants (for example, com, alfalfa, sunflower, Brassica, soybean, cotton, safflower, peanut, sorghum, wheat, millet, tobacco, etc.). In other embodiments, corn and soybean plants and sugarcane plants are optimal, and in yet other embodiments corn plants are optimal.

Stacking of Traits in Transgenic Plant Transgenic plants may comprise a stack of one or more target polynucleotides as set forth in SEQ ID NOS.: 1 -53 or 107-254, or variants or fragments thereof, or complements thereof, as disclosed herein with one or more additional polynucleotides resulting in the production or suppression of multiple polypeptide sequences. Transgenic plants comprising stacks of polynucleotide sequences can be obtained by either or both of traditional breeding methods or through genetic engineering methods. These methods include, but are not limited to, breeding individual lines each comprising a polynucleotide of interest, transforming a transgenic plant comprising an expression construct comprising various target polynucleotides as set forth in SEQ ID NOS. : 1-53 or 107-254, or encoding silencing elements directed to such target sequence variants or fragments thereof, or complements thereof, as disclosed herein with a subsequent gene and co-transformation of genes into a single plant cell. As used herein, the term "stacked" includes having the multiple traits present in the same plant (i.e., both traits are incorporated into the nuclear genome, one trait is incorporated into the nuclear genome and one trait is incorporated into the genome of a plastid or both traits are incorporated into the genome of a plastid). In one non-limiting example, "stacked traits" comprise a molecular stack where the sequences are physically adjacent to each other. A trait, as used herein, refers to the phenotype derived from a particular sequence or groups of sequences. Co- transformation of polynucleotides can be carried out using single transformation vectors comprising multiple polynucleotides or polynucleotides carried separately on multiple vectors. If the sequences are stacked by genetically transforming the plants, the polynucleotide sequences of interest can be combined at any time and in any order. The traits can be introduced simultaneously in a co- transformation protocol with the polynucleotides of interest provided by any combination of transformation cassettes. For example, if two sequences will be introduced, the two sequences can be contained in separate transformation cassettes (trans) or contained on the same transformation cassette (cis). Expression of the sequences can be driven by the same promoter or by different promoters. It is further recognized that polynucleotide sequences can be stacked at a desired genomic location using a site-specific recombination system. See, for example, WO 1999/25821, WO 1999/25854, WO 1999/25840, WO 1999/25855 and WO 1999/25853.

In some embodiments the various target polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107-254, silencing elements directed to such target sequences, and variants or fragments thereof, or complements thereof, as disclosed herein, alone or stacked with one or more additional insect resistance traits can be stacked with one or more additional input traits (e.g., herbicide resistance, fungal resistance, virus resistance, stress tolerance, disease resistance, male sterility, stalk strength, and the like) or output traits (e.g., increased yield, modified starches, improved oil profile, balanced amino acids, high lysine or methionine, increased digestibility, improved fiber quality, drought resistance, and the like). Thus, the polynucleotide embodiments can be used to provide a complete agronomic package of improved crop quality with the ability to flexibly and cost effectively control any number of agronomic pests.

Transgenes useful for stacking include, but are not limited to, to those as described herein below.

i. Transgenes that Confer Resistance to Insects or Disease

(A) Plant disease resistance genes. Plant defenses are often activated by specific interaction between the product of a disease resistance gene (R) in the plant and the product of a corresponding avirulence (Avr) gene in the pathogen. A plant variety can be transformed with cloned resistance gene to engineer plants that are resistant to specific pathogen strains. See, for example, Jones, et al., ( 1994) Science 266:789 (cloning of the tomato Cf-9 gene for resistance to Cladosporium fulvum); Martin, et al., ( 1993) Science 262: 1432 (tomato Pto gene for resistance to Pseudomonas syringae pv. tomato encodes a protein kinase); Mindrinos, et al., ( 1994) Cell 78: 1089 (Arabidopsis RSP2 gene for resistance to Pseudomonas syringae), McDowell and Woffenden, (2003) Trends Biotechnol. 21(4): 178-83 and Toyoda, et al., (2002) Transgenic Res. 1 1(6):567-82. A plant resistant to a disease is one that is more resistant to a pathogen as compared to the wild type plant.

(B) Genes encoding a Bacillus thuringiensis protein, a derivative thereof or a synthetic polypeptide modeled thereon. See, for example, Geiser, et al , (1986) Gene 48: 109, who disclose the cloning and nucleotide sequence of a Bt delta-endotoxin gene. Moreover, DNA molecules encoding delta-endotoxin genes can be purchased from American Type Culture Collection (Rockville, Md.), for example, under ATCC^® Accession Numbers 40098, 67136, 31995 and 31998.

Pesticidal proteins also include toxin complex (TC) proteins, obtainable from organisms such as Xenorhabdus, Photorhabdus and Paenibacillus (see, US Patent Numbers 7,491,698 and 8,084,418). Some TC proteins have "stand alone" insecticidal activity and other TC proteins enhance the activity of the stand-alone toxins produced by the same given organism. The toxicity of a "stand-alone" TC protein (from Photorhabdus, Xenorhabdus or Paenibacillus, for example) can be enhanced by one or more TC protein "potentiators" derived from a source organism of a different genus. There are three main types of TC proteins. As referred to herein, Class A proteins ("Protein A") are stand-alone toxins.

In maize, this, for example, could be accomplished, by cloning and then re -introducing DNA associated with one or more of the alleles, such as the LPA alleles, identified in maize mutants characterized by low levels of phytic acid, such as in WO 2005/1 13778 and/or by altering inositol kinase activity as in WO 2002/059324, US Patent Application Publication Number 2003/000901 1, WO 2003/027243, US Patent Application Publication Number 2003/0079247, WO 1999/05298, U.S. Pat.

No. 6,531,648. which is incorporated by reference for this purpose) and/or a gamma zein knock out or mutant such as cs27 or TUSC27 or en27 (see, U.S. Pat.

No. 6,803,498, WO 2001/79516. iv. Genes that Control Male-Sterility

There are several methods of conferring genetic male sterility available, such as multiple mutant genes at separate locations within the genome that confer male sterility, as disclosed in U.S. Pat. Nos. 4,654,465 and 4,727,219 to Brar, et al., and chromosomal translocations as described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,51 1. In addition to these methods, Albertsen, et al., U.S. Pat. No. 5,432,068, describe a system of nuclear male sterility which includes: identifying a gene which is critical to male fertility; silencing this native gene which is critical to male fertility; removing the native promoter from the essential male fertility gene and replacing it with an inducible promoter; inserting this genetically engineered gene back into the plant; and thus creating a plant that is male sterile because the inducible promoter is not "on" resulting in the male fertility gene not being transcribed. Fertility is restored by inducing or turning "on", the promoter, which in turn allows the gene that confers male fertility to be transcribed. Non-limiting examples include: (A) Introduction of a deacetylase gene under the control of a tapetum-specific promoter and with the application of the chemical N-Ac-PPT (WO 2001/29237); (B) Introduction of various stamen-specific promoters (WO 1992/13956, WO 1992/13957); and (C) Introduction of the barnase and the barstar gene (Paul, et al., ( 1992) Plant Mol. Biol. 19:61 1-622). For additional examples of nuclear male and female sterility systems and genes, see also, U.S. Pat. Nos. 5,859,341 ; 6,297,426; 5,478,369; 5,824,524; 5,850,014 and 6,265,640. v. Genes that Create a Site for Site Specific DNA Integration.

This includes the introduction of FRT sites that may be used in the FLP/FRT system and/or Lox sites that may be used in the Cre/Loxp system. For example, see, Lyznik, et al., (2003) Plant Cell Rep 21 : 925-932 and WO 1999/25821. Other systems that may be used include the Gin recombinase of phage Mu (Maeser, et al., ( 1991) Vicki Chandler, The Maize Handbook ch. 1 18 (Springer-Verlag 1994), the Pin recombinase of E. coli (Enomoto, et al., 1983) and the R/RS system of the pSRi plasmid (Araki, et al, 1992). vi.

IX. Methods of Use

Methods disclosed herein comprise methods for controlling a plant insect pest, such as a Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest. In one embodiment, the method comprises feeding or applying to a plant insect pest a composition comprising a silencing element dislcosed herein, wherein said silencing element, when ingested or contacted by a plant insect pest (i.e., but not limited to, a Coleopteran plant pest including a Diabrotica plant pest, such as, D. virgifera virgifera, D. barberi, D. virgifera zeae, D. speciosa, or D. undecimpunctata howardi), reduces the level of a target polynucleotide of the pest and thereby controls the pest. The pest can be fed the silencing element in a variety of ways. The silencing element may be fed to male, female, or both sexes of a pest. For example, in an embodiment, a polynucleotide encoding a silencing element, i.e. , a silencing element targeting one or more polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107-254, is introduced into a plant. As the plant pest feeds on the plant or part thereof expressing these sequences, the silencing element is delivered to the pest at larval, adult, or at any or all developmental stages. In one embodiment, the methods and compositions described herein further comrprise a transgenic plant comprising a silencing element disclosed herein, wherein the silencing element has sterilization activity at larval, adult or at any or all developmental stages. When the silencing element is delivered to the plant in this manner, it is recognized that the silencing element can be expressed constitutively or alternatively, it may be produced in a stage-specific manner by employing the various inducible or tissue-preferred or developmentally regulated promoters that are discussed elsewhere herein. In certain embodiments, the silencing element is expressed in the roots, stalk or stem, leaf including pedicel, xylem and phloem, fruit or reproductive tissue, silk, flowers and all parts therein or any combination thereof. Sterile insects may result from exposure to silencing elements in this manner and hence sterilize insects of opposite the sex through competitive mating or SIT.

In another method, a composition comprising at least one silencing element disclosed herein is applied to a plant. In such embodiments, the silencing element may be formulated in an agronomically suitable and/or environmentally acceptable carrier, which is preferably, suitable for dispersal in fields. In some embodiments, silencing elements targeting different insect stages, pathways, and sexes may be combined for sterility and insecticidal activities. In one embodiment, the silencing elements disclosed herein may be mixed with pesticidal chemicals by tank mix. In addition, the carrier may also include compounds that increase the half-life of the composition. In certain embodiments, the composition comprising the silencing element is formulated in such a manner such that it persists in the environment for a length of time sufficient to allow it to be delivered to a plant insect pest. In such embodiments, the composition can be applied to an area inhabited by a plant insect pest. In one embodiment, the composition is applied externally to a plant (i.e., by spraying a field) to protect the plant from pests. Sterile insects that result from exposure to silencing elements may sterilize insects of opposite sex through competitive mating or SIT.

In certain embodiments, the disclosed polynucleotides or constructs can be stacked with any combination of polynucleotide sequences of interest in order to create plants with a desired trait. A trait, as used herein, refers to the phenotype derived from a particular sequence or groups of sequences. For example, the polynucleotides described herein may be stacked with any other polynucleotides encoding polypeptides having pesticidal and/or insecticidal activity, such as other Bacillus thuringiensis toxic proteins (described in U.S. Patent Nos. 5,366,892; 5,747,450; 5,737,514; 5,723,756; 5,593,881; and Geiser et al. (1986) Gene 48: 109), lectins (Van Damme et al. (1994) Plant Mol. Biol. 24:825, pentin (described in U.S. Patent No. 5,981,722), and the like. The combinations generated may also include multiple copies of any one of the polynucleotides of interest. The polynucleotides described herein can also be stacked with any other gene or combination of genes to produce plants with a variety of desired trait combinations including, but not limited to, traits desirable for animal feed such as high oil genes (e.g., U.S. Patent No. 6,232,529); balanced amino acids (e.g., hordothionins (U.S. Patent Nos. 5,990,389; 5,885,801; 5,885,802; and 5,703,409); barley high lysine (Williamson et al. (1987) Eur. J. Biochem. 165:99-106; and WO 98/20122) and high methionine proteins (Pedersen et al. (1986) J. Biol. Chem. 261 :6279; Kirihara et al. (1988) Gene 71 :359; and Musumura et al. (1989) Plant Mol. Biol. 12: 123)); increased digestibility (e.g., modified storage proteins (U.S. Application Serial No. 10/053,410, filed November 7, 2001); and thioredoxins (U.S. Application Serial No. 10/005,429, filed December 3, 2001)).

Disclosed polynucleotides can also be stacked with traits desirable for disease or herbicide resistance (e.g., fumonisin detoxification genes (U.S. Patent No. 5,792,931); avirulence and disease resistance genes (Jones et al. (1994) Science 266:789; Martin et al. (1993) Science 262: 1432; Mindrinos et al. (1994) Cell 78: 1089); acetolactate synthase (ALS) mutants that lead to herbicide resistance such as the S4 and/or Hra mutations; inhibitors of glutamine synthase such as phosphinothricin or basta (e.g., bar gene); and glyphosate resistance (EPSPS gene)); and traits desirable for processing or process products such as high oil (e.g., U.S. Patent No. 6,232,529 ); modified oils (e.g., fatty acid desaturase genes (U.S. Patent No. 5,952,544; WO 94/11516)); modified starches (e.g., ADPG pyrophosphorylases (AGPase), starch synthases (SS), starch branching enzymes (SBE), and starch debranching enzymes (SDBE)); and polymers or bioplastics (e.g., U.S. Patent No. 5.602,321; beta-ketothiolase, polyhydroxybutyrate synthase, and acetoacetyl-CoA reductase (Schubert et al. (1988) J. Bacteriol. 170:5837-5847) facilitate expression of polyhydroxyalkanoates (PHAs)); the disclosures of which are herein incorporated by reference. One could also combine the polynucleotides with polynucleotides providing agronomic traits such as male sterility (e.g., see U.S. Patent No. 5.583,210), stalk strength, drought resistance (e.g., U.S. Patent No. 7,786,353), flowering time, or transformation technology traits such as cell cycle regulation or gene targeting (e.g., WO 99/61619, WO 00/17364, and WO 99/25821).

These stacked combinations can be created by any method including, but not limited to, cross-breeding plants by any conventional or TopCross methodology, or genetic transformation. If the sequences are stacked by genetically transforming the plants (i.e., molecular stacks), the polynucleotide sequences of interest can be combined at any time and in any order. For example, a transgenic plant comprising one or more desired traits can be used as the target to introduce further traits by subsequent transformation. The traits can be introduced simultaneously in a co- transformation protocol with the polynucleotides of interest provided by any combination of transformation cassettes. For example, if two sequences will be introduced, the two sequences can be contained in separate transformation cassettes (trans) or contained on the same transformation cassette (cis). Expression of the sequences can be driven by the same promoter or by different promoters. In certain cases, it may be desirable to introduce a transformation cassette that will suppress the expression of the polynucleotide of interest. This may be combined with any combination of other suppression cassettes or overexpression cassettes to generate the desired combination of traits in the plant. It is further recognized that polynucleotide sequences can be stacked at a desired genomic location using a site-specific recombination system. See, for example, W099/25821, W099/25854, WO99/25840, W099/25855, and W099/25853.

X. Insect Resistance Management Methods

Methods disclosed herein comprise methods for controlling a plant insect pest, such as a Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest, such as insect resistance management. Insect resistance management (IRM) is the term used to describe practices aimed at reducing the potential for insect pests to become resistant to a pesticide. Maintenance of Bt (or other pesticidal protein, chemical, or biological) IRM is of great importance because of the threat insect resistance poses to the future use of Bt plant-incorporated protectants and Bt technology as a whole. Specific IRM strategies, such as the high dose/structured refuge strategy, delay insect resistance to specific Bt proteins produced in corn, cotton, and potatoes. However, such strategies result in portions of crops being left susceptible to one or more pests in order to ensure that non- resistant insects develop and become available to mate with any resistant pests produced in protected crops. Accordingly, from a farmer/producer's perspective, it is highly desirable to have as small a refuge as possible and yet still manage insect resistance, in order that the greatest yield be obtained while still maintaining the efficacy of the pest control method used, whether Bt, chemical, some other method, or combinations thereof. An often used IRM strategy is the planting of a refuge (a portion of the total acreage using non-Bt/pesticidal trait seed), as it is commonly-believed that this will delay the development of insect resistance to pesticidal traits by maintaining insect susceptibility. The theoretical basis of the refuge strategy for delaying resistance hinges on the assumption that the frequency and recessiveness of insect resistance is inversely proportional to pest susceptibility; resistance will be rare and recessive only when pests are very susceptible to the toxin, and conversely resistance will be more frequent and less recessive when pests are not very susceptible. Furthermore, the strategy assumes that resistance to Bt is recessive and is conferred by a single locus with two alleles resulting in three genotypes: susceptible homozygotes (SS), heterozygotes (RS), and resistant homozygotes (RR). It also assumes that there will be a low initial resistance allele frequency and that there will be extensive random mating between resistant and susceptible adults. Under ideal circumstances, only rare RR individuals will survive a pesticidal toxin produced by the crop. Both SS and RS individuals will be susceptible to the pesticidal toxin. A structured refuge is a non-Bt/pesticidal trait portion of a grower's field or set of fields that provides for the production of susceptible (SS) insects that may randomly mate with rare resistant (RR) insects surviving the pesticidal trait crop, which may be a Bt trait crop, to produce susceptible RS heterozygotes that will be killed by the Bt/pesticidal trait crop. An integrated refuge is a certain portion of randomly planted non-Bt/pesticidal trait portion of a grower's field or set of fields that provides for the production of susceptible (SS) insects that may randomly mate with rare resistant (RR) insects surviving the pesticidal trait crop to produce susceptible RS heterozygotes that will be killed by the pesticidal trait crop Each refuge strategy will remove resistant (R) alleles from the insect populations and delay the evolution of resistance.

Another strategy to reduce the need for refuge is the pyramiding of traits with different modes of action against a target insect pest. For example, Bt toxins that have different modes of action stacked in one transgenic plant are able to have reduced refuge requirements. Different modes of action in a stacked combination also maintains the durability of each trait, as resistance is slower to develop to each trait.

Currently, the size, placement, and management of the refuge are often considered critical to the success of refuge strategies to mitigate insect resistance to the Bt/pesticidal trait produced in corn, cotton, soybean, and other crops. Because of the decrease in yield in refuge planting areas, some farmers choose to eschew the refuge requirements, and others do not follow the size and/or placement requirements. These issues result in either no refuge or less effective refuge, and a corresponding risk of the increase in the development of resistance pests.

Accordingly, there remains a need for methods for managing pest resistance in a plot of pest resistant crop plants. It would be useful to provide an improved method for the protection of plants, especially corn or other crop plants, from feeding damage by pests. It would be particularly useful if such a method would reduce the required application rate of conventional chemical pesticides, and also if it would limit the number of separate field operations that were required for crop planting and cultivation. In addition, it would be useful to have a method of deploying a transgenic refuge that eliminates the above-described problems with regard to compliance that dilute or remove the efficacy of many resistance management strategies.

One embodiment relates to a method of reducing the development of resistant pests comprising providing a plant protection composition to a plant (Bt toxin, transgenic insecticidal protein, other insecticidal proteins, chemical insecticides, insecticidal biological entomopathogens, etc.) and contacting the plant pest with a silencing element, i. e. , of a silencing element targeting one or more polynucleotides as set forth in SEQ ID NOS. : 1-53 or 107-254, wherein the silencing element, i.e. , of a silencing element targeting one or more polynucleotides as set forth in SEQ ID NOS. : 1-53 or 107-254, produces a decrease in expression of one or more of the sequences in the target pest and controls the pest and pest population by insect sterilization or SIT.

A further embodiment relates to a method of increasing the durability of plant pest compositions comprising providing a plant protection composition to a plant (Bt toxin, transgenic insecticidal protein, other insecticidal proteins, chemical insecticides, insecticidal biological entomopathogens etc.) and contacting a plant pest with the sterilization silencing element, i. e. , of one or more polynucleotides as set forth in SEQ ID NOS. : 1-53 or 107-254, or complements thereof, an expression construct comprising a sequence as set forth in SEQ ID NOS.: 1 -53 or 107-254, or complements thereof, or silencing elements targeting said polynucleotides, produces a decrease in expression of one or more of the sequences in the target pest and controls the pest and pest population by insect sterilization or sterile insect technique. In another embodiment, the refuge planted as a strip, a block, or integrated with the trait seed comprises a plant further comprising a sterilization silencing element (for example, a silencing element targeting one or more polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107-254).

In a still further embodiment, the refuge required may be reduced or eliminated by the presence of a sterilization silencing element applied to the non-refuge plants. In another embodiment, the refuge or non-refuge may include a silencing element, i.e. , of one or more polynucleotides as set forth in SEQ ID NOS. : 1-53 or 107-254, or complements thereof, an expression construct comprising a sequence as set forth in SEQ ID NOS.: 1-53 or 107-254, or complements thereof, or silencing elements targeting said polynucleotides, as a spray, bait, lure, or as a different transgenic plant.

In a further embodiment, a pest insect is feed a diet comprising one or more polynucleotides as set forth in SEQ ID NOS.: 1-53 or 107-254, or complements thereof, an expression construct comprising a sequence as set forth in SEQ ID NOS. : 1-53 or 107-254, or complements thereof, or silencing elements targeting said polynucleotides, and said insects are released onto plants at 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 days following feeding. In a still further embodiment, the pest insect is a female pest insect. In a yet further embodiment, the pest insect is a pest insect, and the pest insect is fed during a larval or adult stage. Insect sterilization may result from male or female sterility, mating of sterile insects, reduction of sperm count, egg production or viability.

In certain embodiments, the compositions and methods disclosed herein, targeting a sterile gene via RNAi technology, and stacking a polynucleotide encoding a silencing element disclosed herein with an insecticidal protein in a transgenic plant may provide effective control of Coleoptera and potentially extend the durability of Coleopteran insecticidal traits. The extended durability may be a consequence of minimizing the transmission of resistance alleles from Coleopteran beetles that were able to complete their developmental life cycle while feeding on transgenic roots expressing a stack of an insecticidal protein(s) and a RNAi sterility trait disclosed herein.

Current IRM strategy requires a high dose of Bt toxins to minimize insect resistance development. Due to phyto-toxicity, it can be difficult to achieve the required high dose. Integrated pest management (IPM) by different means of insect control may be used to delay insect resistance exposed to a sub-optimal dose of protein toxin, such as a Bt toxin. RNAi mediated SIT may be deployed as part of an IPM strategy.

As used herein, the term "pesticidal" is used to refer to a toxic effect against a pest (e.g.,

CRW), and includes activity of either, or both, an externally supplied pesticide and/or an agent that is produced by the crop plants. As used herein, the term "different mode of pesticidal action" includes the pesticidal effects of one or more resistance traits, whether introduced into the crop plants by transformation or traditional breeding methods, such as binding of a pesticidal toxin produced by the crop plants to different binding sites (i.e., different toxin receptors and/or different sites on the same toxin receptor) in the gut membranes of corn rootworms or through RNA interference.

Example 2: Western Corn Rootworm (WCRW) Adult Sterilization by VgR dsRNA.

Artificial diet for WCRW adults was prepared using a modified protocol (Rangasamy M et al.

(2012). Pest Manag. Sci. 68(4):587-91; and Nowatzki TM, et al. (2006) J Econ. Entomol. 99(3):927- 30). The modified diet was designed for use in the diet incorporated bioassay described herein below (25 μΐ test sample: 75 μΐ prepared diet) and was produced using standard 96-well micro-titer plates. WCRW adults consumed significant proportions of the diet within 24 hours, and control mortality remains < 15% during the 2-3 week study period. For all the bioassays described herein, WCRW life stages (adults and larvae) were kept under standard conditions, for example, Jackson, J.J. (1986), pp 25-48. In Krysan J. L. and Miller T.A. (eds): Methods for the Study of pest Diabrotica. Springer- Verlag, New York. 260 pp, and Branson, T.F., et al. (1988), J. Econ. Entomal. 81(1): 410-414 (1988).

Beetles from the same batch were categorized in to two groups. The first test group consisted of male and females of <10 days old (range 2-5 days old) (hereinafter referred to as "younger females"). The younger females were in their preoviposition period (the period before oviposition of the first eggs). The second group consisted of >11 days old and mated females (hereinafter referred to as "older females") and they were in oviposition period (females are ready to lay eggs). For the younger female group 100 beetles (50 females and 50 males) and for the older female group 50 mated females were arranged for each treatment. The following three treatments were compared 1) sterile DI water (control); 2) GFP dsRNA (negative control, GenBank Accession # AY233272.1; SEQ ID NO: 104 herein); and 3) VgR dsRNA fragment 2 (SEQ ID NO: 4). The bioassay was carried out using a diet incorporation methodology. Test samples of GFP dsRNA and VgR dsRNA were prepared separately and 25 μΐ of the respective samples were incorporated into 75 μΐ of modified WCRW adult artificial diet per well in 96-well micro-titer plates for a final concentration of 100 ppm. For control 25 μΐ of sterile DI water was incorporated into 75 μΐ of modified WCRW adult artificial diet per well.

The effects on individual WCRW adult beetle were confined using individual wells of 32 cell trays (C-D International, Pitman, NJ) provided with single diet pill (mixture of 25 μΐ test sample and 75 μΐ of modified WCRW adult artificial diet) for 24 hours. After 24 hour, treated adults were collected, counted and transferred to their respective holding cages and provided standard SCRW dry adult diet and water source until the end of the study period (22-25 days).

WCRW eggs were collected daily for 13-14 days starting from 24 hour or 7 days after exposure for the older and younger female group, respectively. Eggs were collected using oviposition dish. Collected eggs were incubated in a heat and humidity controlled growth chamber (25 ^°C, 65% ± 5% reltaive humidity (RH)) with controlled light/dark cycles (16 hr light:8 hr darkness) for 12-14 days before processing.

Several small aliquots of egg-agar suspensions were dispensed onto a hatch plate (petri-dish containing 2% water agar and two layers of filter paper) for counting and /or hatch test depending on the number of eggs obtained for a given day. For the egg hatch test, samples (1-6) each containing 25 μΐ of egg-agar suspension were dispensed onto the hatch plate as described above and the lids secured with micropore tape to avoid larval escape. Total number of eggs in each 25 μΐ sample was counted prior incubation. Egg hatch plates were then incubated in a heat and humidity controlled growth chamber (25 ^°C, 65% ± 5% RH) with controlled light/dark cycles (16 hr light: 8 hr darkness) for three days. Egg hatch was counted over three days period by counting the number of eggs showing larval emergence hole. For each treatment, four treated female and male beetles (younger female group) and four females (older female group) were sampled for gene suppression at 4 and 8 days after exposure for the older and younger female group respectively.

For dsRNA in vitro transcript ("IVT") production, PCR was performed using target specific forward and reverse primers (see Table 2 below) with a T7 promoter sequence at the 5' end of each primer. The dsRNA samples were produced from PCR template using Ambion Megascript High Yield Transcription Kit (Thermo Fisher Scientific, Grand Island, NY). An agarose gel was run to check for yield and product size. For real time qRTPCR assay, total RNA was extracted with MirVana miRNA Isolation Kit, treated by TURBO DNase Kit, assayed by Superscript® III Platinum® One-Step qRT-PCR Kit with ROX according to manufacturer's instructions (Thermo Fisher Scientific). Relative expression was derived by delta delta Ct method (Livak, K. J. and T. D. Schmittgen (2001). Methods 25(4): 402-408) using WCRW RPS10 as reference (i.e., SEQ ID NO: 8 in US 2011/0054007; also SEQ ID NOs.: 102 and 103, ORF and transcript, respectively, herein).

Table 2: Primer Sequences IVT Production.

Data obtained using these methods are shown in FIGs. 1A-1D. In particular, FIG. 1A shows the total number of eggs produced within 13-14 days by treatment and age group. In the experiment shown in FIG. 1A, the younger female group contained 50 pairs of male and female beetles, whereas the older female group had 50 mated female beetles. The data in FIG. 1A show that ingestion of the VgR dsRNA significantly reduced the total number of eggs produced during the test period. FIG. IB shows the average number of eggs produced per female/day during 13-14 day oviposition period by treatment and age group. The box plot shows 4 quartiles, average, and 95% confidence interval of the mean. The data show that in both younger and older females, ingestion of the VgR dsRNA reduced the average number of egges produced per day. FIG. 1C shows the effect of various treatments on overall average egg hatch rate. Data represents 13-14 days egg collection period; n = 6 replication/treatment/day; 5-45 eggs/replication depending on the day (p < 0.001). Gene suppression analysis is shown in FIG. ID for analysis carried out on WCRW adult beetles 8 days after treatment of female and male insects for younger age group and 4 days after treatment of female insects for older age group. Relative expression of VgR is shown from 4 individual insects for each treatment using WCRW RPS10 gene as reference and untreated older beetle as normalizes The box plot shows 4 quartiles, average, median, and 95% confidence interval of the mean by treatment and age group.

Example 3: WCRW Sterilization by Treatment of 3rd Instar Larvae with VgR dsRNA.

The effect of treatment of larva on WCRW sterilization by VgR dsRNA (VgR dsRNA fragment 2) was assessed. The study was carried out using 3rd instar larvae that were harvested from corn mats and acclimatized on standard WCRW larval diet for 24 h. About 192 larvae were exposed to water and 75 ppm VgR dsRNA fragment 2 (SEQ ID NO: 4) for 1 day using the diet incorporation method described above (25 μΐ dsRNA and 75 μΐ artificial WCRW larval diet). Treated larvae were placed in pupation medium for 15 days. Emerged adults were collected, counted, and transferred to their respective holding cages and provided standard SCRW dry adult diet with a water source until the end of the study period (22-25 days). Beetle holding cages were kept at room temperature (usually from 22-25^°C) with no RH control. No intentional light/dark control but cages were getting roughly 16:8 Dark and light condition. Beetle holding cages were cleaned maintained twice a week and each time the beetles recived new food and water agar. Adult beetles were kept for a total of 26 days. Each cage received oviposition dishes after 10 days preoviposition period and eggs were collected over a period of for 16 days oviposition period, and processed following the method described above.

Representative data for this study are shown in FIGs. 2A and 2B. The average total number of eggs produced per female and the average number of viable eggs produced per female are shown in FIG. 2A. Eggs from 15-42 female adult beetles were counted for each indicated treatment. The box plot of shows 4 quartiles, average, median, and 95% confidence interval of the mean for each treatment. The data show that for the VgR dsRNA exposed group, the viable egg production remained very low throughout the study period. It should be noted that treatment with VgR dsRNA did not affect adult emergence, and that mortality of adult beetles in the VgR dsRNA group was negligible.

Representative data for VgR gene suppression analysis is shown in FIG. 2B. The data were obtained for 10-day old (n=4) and 28-day old (n=15) beetles, which represents day 40 and day 58, respectively, following treatment of the 3^rd instar larvae. The box plot of relative expression by qRTPCR shows 4 quartiles, average, median, and 95% confidence interval of the mean for each treatment in 10 and 28 day old beetles. The data were normalized to untreated 3rd instar larvae. The data show decreasesd relative expression of VgR in both age groups.

Example 4: Dose Response of WCRW Sterilization and Gene Suppression by VgR dsRNA Treatment.

The dose response effect of dsRNA treatment was determined in younger and older adult femals. The older female group (>11 days old) was collected and exposed VgR dsRNA using the diet incorporation methodology described above. The treatment groups were exposed for 24 hours. The VgR dsRNA was complementary to SEQ ID NO: 3, and the concentrations tested were as follows: 0, 0.01 ppm, 0.1 ppm, 1 ppm, 10 ppm and 75 ppm. The treatment groups consisted of about 40 - 48 females for each dose level. Egg production was assessed starting 24 hours after exposure and continued for 18 days. For each treatment, the total number of female beetles used for egg production varies from 40-48 (days 1-6) and 20-28 (days 7-18). Eggs were handled and processed following the methods described above. Six day after exposure 20 treated females were retrieved from each treatment and were used for gene suppression analysis.

The details for each dose treatment group (e.g. number of total eggs analyzed, number of viable eggs, and net reduction in fecundity) are given in FIG. 3A. Eggs were collected and counted over the 18 day oviposition period. The net reduction in fecundity (NRF) of VgR dsRNA -treated females relative to control (water exposed females) was estimated using the following formula:

NRF (%) = [ 1 -(NVEt / NVEwc)] * 100,

where "NRF" represents the net reduction in fecundity as a percent; "NVEt" repredsents the number of viable eggs in the treatment group; and "NVEwc" represents the number of viable eggs in water (control) treated group. The data show a significant reduction in egg production after 10 days of exposure to the VgR dsRNA (see eggs/ female day 10 -18 in FIG. 3A). The data further show that egg production and viability of eggs were negatively correlated with VgR dsRNA doses. The net reduction in fecundity was positively correlated with increased vgR dsRNA doses. FIG. 3B shows a box plot of percentage of overall egg hatch rates by dose for the 18 day egg collection period; n = 1-4 replication/treatment/day; 5-478 eggs/replication depending on the day and availability of eggs. The data in FIG. 3C show a box plot of relative expression of VgR at day 6 after VgR dsRNA treatment at different doses. The data in FIG. 3C show the correlation of increasing dose with a larger decrease in expression of VgR. The treatment group data were normalized to the expression for untreated beetles.

Example 5: Gene Suppression Analysis of VgR Fragments.

The effect of five distinct VgR dsRNA target fragments was assessed. FIG. 4A shows schematically the relative position of the different fragments tested aligned against SEQ ID NO: 2. The target fragments tested were as follows: Fragl is VgR fragment 1 (SEQ ID NO: 3); Frag2 is VgR fragment 2 (SEQ ID NO: 4); Frag3 is VgR fragment 3 (SEQ ID NO: 5); Frag4 is VgR fragment 4 (SEQ ID NO: 6); and Frag5 is VgR fragment 5 (SEQ ID NO: 7). Each VgR dsRNA fragment was tested using the diet incorporation methodology described above with WCRW female beetles with the VgR dsRNA at 100 ppm in the diet plug. The beetles were treated individually for one day and fed with standard diet with no dsRNA for an additional six days. The individual beetles were then collected and flash frozen in in liquid nitrogen. For the qRTPCR assays, at least 3 insects were used for each treatment group using the primer sequences indicated in Table 3 below. FIG. 4B shows a box plot of the relative VgR expression at day 6 after treatment with the indicated dsVgR fragments or control treatment (i.e. , ddH20 and dsGUS (SEQ ID NO: 105, herein), as indicated, replacing the VgR dsRNA in the diet) using 5' qRTPCR assay. The box plot shows four quartiles: average (horizontal solid line), median (horizontal dash line), and 95% confidence interval of the mean are shown. Similar results were also obtained with Mid- and 3 '-qRTPCR assays. The data in the treatment groups were normalized to data obtained from qRTPCR from untreated 3rd instar larvae.

Table 3: Primer Sequences Gene Suppression Analysis.

Example 6: WCRW VgR Fragment Screen by Gene Suppression Analysis. Additional VgR dsRNA fragments covering the entirety of the coding DNA sequence of SEQ ID NO: 2 were assessed for ability to suppress expression of VgR. The fragments tested are shown aligned against SEQ ID NO: 2 in FIG. 5A, and the various sequence names correspond to the fragment ID shown in Table 1. Each VgR dsRNA fragment was tested using the diet incorporation methodology described above with WCRW female beetles with the VgR dsRNA at 100 ppm in the diet plug. The beetles were treated individually for one day and fed with standard diet with no dsRNA for 6 additional days. The individual beetles were then collected and flash frozen in in liquid nitrogen. For the qRTPCR assays, at least 6 insects were used for each treatment group. FIGS. 5B- 5D box plots of the relative VgR expression at day 6 after treatment with the indicated dsVgR fragments or control treatment (i.e. , ddH20 and dsGUS, as indicated, replacing the VgR dsRNA in the diet) using 5' qRTPCR assay. The data in the treatment groups were normalized to data obtained from qRTPCR from water treated beetles. Two qRTPCR assays (5'- and Mid-qRTPCR assays) were used to avoid overlapping of VgR fragment and PCR amplicon. Example 7: Agrobacterium-medi&ted Transformation of Maize

For Agrobacterium- ediated transformation of maize with a silencing element of the invention, the method of Zhao is employed (U.S. Patent No. 5,981,840, and PCT patent publication W098/32326; the contents of which are hereby incorporated by reference). Such as a construct can, for example, express a long double stranded RNA of the target sequence set forth in table 1. Such a construct can be linked to a promoter. Briefly, immature embryos are isolated from maize and the embryos contacted with a suspension of Agrobacterium, where the bacteria are capable of transferring the polynucleotide comprising the silencing element to at least one cell of at least one of the immature embryos (step 1 : the infection step). In this step the immature embryos are immersed in an Agrobacterium suspension for the initiation of inoculation. The embryos are co-cultured for a time with the Agrobacterium (step 2: the co-cultivation step). The immature embryos are cultured on solid medium following the infection step. Following this co-cultivation period an optional "resting" step is contemplated. In this resting step, the embryos are incubated in the presence of at least one antibiotic known to inhibit the growth of Agrobacterium without the addition of a selective agent for plant transformants (step 3: resting step). The immature embryos are cultured on solid medium with antibiotic, but without a selecting agent, for elimination of Agrobacterium and for a resting phase for the infected cells. Next, inoculated embryos are cultured on medium containing a selective agent and growing transformed callus is recovered (step 4: the selection step). The immature embryos are cultured on solid medium with a selective agent resulting in the selective growth of transformed cells. The callus is then regenerated into plants (step 5 : the regeneration step), and calli grown on selective medium are cultured on solid medium to regenerate the plants. Example 8: WCRW VgR Transgenic Feeding Bioassay.

Transgenic maize plants for VgR Fragl, Frag2 and Frag3 were generated using the methods described herein above and used in adult feeding bioassays for gene suppression analysis in WCRW beetles as described hereina above. The expression levels of the VgR fragments in planta were determined in leaf samples using in vitro transcription (IVT) products as controls. The expression analyses were carried out according to manufacturer's instruction (Quantigene 2.0 Assay, Affymetrix, Santa Clara, CA 95051). The average VgR fragment expression level (pg VgR fragment/mg fresh plant weight) in leaves is indicated at below each graph in FIGs. 6A and 6B. FIG. 6A shows data obtained from three young plants at about the V4 growth stage for either a non-transgenic control (NTG) or the indicated transgenic planted expressing the indicated fragment VgR Fragl (SEQ ID NO: 3), Frag2 (SEQ ID NO: 4), and Frag3 (SEQ ID NO: 5). The test plants were infested with at least 14 young female beetles in cages. The beetles were collected at 8 days after feeding and used for gene suppression analysis. Data were normalized to expression levels obtained in beetles exposed NTG plants. FIG. 6B shows results obtained using either non-transgenic control plants or transgenic plants expressing the indicated VgR dsRNA fragment. The individual Rl maize plants were infested with at least 6 young female beetles in cages. Beetles were collected 12 days after feeding for VgR expression analysis. Each fragment and control is represented by 2 plants used for feeding and more than 12 insects used in gene suppression analysis, and data were normalized to data obtained from non-trangenic control plants exposed undedr similar conditions.

Example 9: WCRW Adult VgR Transgenic Exposure Bioassay.

At least 32 pairs of newly emerged adult beetles were exposed to 8 days to above ground plant part of Tl transgenic events or non-transgenic (NTG) control plants. Beetles were recollected and at least 13-37 female beetles were arranged in a cage for each treatment and maintained for 15 days for fecundity assessment. Transgenic constructs expressed VgR Fragl (SEQ ID NO: 3), Frag2 (SEQ ID NO: 4), or Frag3 (SEQ ID NO: 5). For each construct 2-4 events were tested (FIG. 7). Each cage received oviposition dish daily and/or at interval of 2-4 days and eggs were processed following the method described in Example 2. Example 10: WCRW Larval VgR Transgenic Exposure Bioassay.

Maize Tl plants expressing silencing elements (targeting SEQ ID NOs: 3, 4, and 5) were transplanted from culture plates into greenhouse flats containing Fafard Superfine potting mix. Three positive individual plants (of same event) were transplanted and maintained in a greenhouse (80°F, 15hr light: 9hr darkness) and watered as needed. When the plants reached the V2 leaf stage, each pot was infested with 200 non-diapausing D. virgifera virgifera eggs. Plants were monitored daily for first beetle emergence. The number of adult D. virgifera virgifera that emerged from each pot was determined in the greenhouse in a similar manner as described by Meihls et al. (2008) PNAS 105: 19177-19182. Adult beetles emerged from Tl transgenic events and non-transgenic (NTG) control plants as in Example 9 were collected every 2 or 3 days and maintained for 15 days for fecundity assessment. For each event three replicate cages containing at least 8 -14 pairs of male and female beetles were arranged. Each cage received oviposition dish every 5 days and eggs were processed following the method described in Example 2 (FIG. 8).

Example 11: WCRW Adult Exposed Sterilization Bioassav and Gene Suppression by

Treatment of dsRNA Targeting BOULE.

Virgin adult beetles were obtained by rearing 3^rd instar larvae individually in a 50mL falcon tube containing the pupation medium. Beetles were sexed upon emergence; starved for 24 hours and exposed at 100 ppm of dsRNA targeting the BOULE target gene (DV-BOULE-FRAG1, SEQ ID NO: 164) or controls (sterile water or GUS dsRNA) using diet incorporated method for one day. Treated beetles were provided untreated diet and kept in solitary confinement for additional 5 days. At least 12 treated beetles of mixed sex were collected in liquid nitrogen for gene suppression analysis. At least 14 pairs (male and female) were arranged for each treatment for subsequent mating and fecundity assessment. Due to delay in mating, oviposition was begun 19 days after emergence and egg production was assessed for 10 days. As shown in FIG. 9A, high dose adult exposure to dsRNA targeting BOULE (BOULE dsRNA, SEQ ID NO: 164) did not affect egg production and hatch rate of the eggs. FIG. 9B shows gene expression in beetles after BOULE dsRNA (SEQ ID NO: 164) treatment. Relative expression by qRTPCR assay was performed as in previous examples.

Example 12: WCRW Beetle Counts from Larval Exposure to Tl Transgenic Plants Expressing dsRNA Targeting BOULE.

Three maize seedlings of V2 leaf stage Tl transgenic events expressing dsRNA targeting

BOULE using DV-BOULE-FRAG 1 (SEQ ID NO: 164) and non-transgenic (NTG) control plants were infested with 200 WCR eggs per pot in greenhouse. Approximately one month after infestation, beetles emerged from each pot were captured every 2 or 3 days over 10 days. Average beetle numbers for the total and each sex (Male and Female) from at least 9 pots per event and 10 NTG control pots are shown. The box plot shows four quartiles, average (horizontal dash line), median (horizontal solid line), and 95% confidence interval of the mean. The results suggest that exposure of WCRW larvae to transgenic events expressing DV-BOULE FRAG1 (SEQ ID NO: 164) dsRNA did not affect adult emergence pattern when compared to NTG plants (FIG. 10). Average expression levels of the BOULE fragment in planta for each event were determined in root samples using in vitro transcription (IVT) product as control as described in Example 8. Example 13: WCRW Larval Exposure to Transgenic Tl Plants Expressing dsRNA Targeting BOULE Caused Adult Sterilization.

Beetles emerged from Tl transgenic events expressing DV-BOULE-FRAG1 (SEQ ID NO: 164) dsRNA and non-transgenic (NTG) control plants were maintained for 25 days for fecundity assessment. For each event three replicate cages containing at least 8 -14 pairs of male and female beetles were arranged. Each cage received oviposition dish every 5 days and eggs were processed following the method described in Example 2 except that egg hatch duration was extended up to 8 days. FIG. 11A shows the effect of larval exposure to transgenic plants expressing DV-BOULE- FRAG1 (SEQ ID NO: 164) dsRNA on the overall average egg production per female and average viable eggs produced per female from emerged beetles. FIG. 1 IB shows the effect of larval exposure to transgenic plants expressing DV -BOULE -FRAG 1 (SEQ ID NO: 164) dsRNA on hatch rate of eggs obtained from the emerged beetles. FIG. 11C indicates the effect of larval exposure to transgenic plants expressing DV -BOULE -FRAG 1 (SEQ ID NO: 164) dsRNA on net reduction in fecundity of emerged adult beetles relative to NTG control.

Over 400 3rd instar larvae were exposed to lppm of the respective dsRNA samples (DV- MAEL-FRAG1, SEQ ID NO: 46; DV-NCLB-FRAGl, SEQ ID NO: 45; and DV-CUL3 -FRAG 1 , SEQ ID NO: 44) following the method described on Example 3. Water and GUS treatment were included as experimental controls. Treated larvae were separated into four groups, each containing about 95 to 100 treated larvae and placed in pupation medium for 15 days. Emerged adults were collected, counted, and transferred to their respective holding cages and handled as described in Example 3. After 10 days of oviposition period the number beetles in each replicate cage was adjusted to at least 12-16 pairs (male and female) and fecundity was assessed for 15 days. At least 2-3 replicate cages were setup for each treatment. The average total number of eggs produced per female, the average number of viable eggs produced per female, the average egg hatch rate; average reduction in egg production and net reduction in fecundity (both relative to water control) are shown in FIG. 12. Example 15: WCRW Sterile Gene Screening by 3^rd Instar Sterilization Bioassay at 50ppm.

The effect of treatment of larvae on WCRW sterilization by dsRNA targeting various genes of interest (GOI) was assessed using 3^rd instar. A set of 8-14 dsRNA samples including water and GUS control was tested at a time. The study was carried out using 10 day old 3rd instar larvae that were harvested from corn mats and acclimatized on standard WCRW larval diet for 24 hours. Diet incorporation method was used for exposing larvae to 50 ppm final concentration of the respective test dsRNA samples in 2mL per well of 6-well plate. A total of three 6-well plates were prepared for each sample and about 312 larvae were exposed to water or 50 ppm of target dsRNA fragment (GOI) for 1 day (~ 104 larvae / plate; 16 -18 larvae / well). After exposure, ~ 10 3^ri instar larvae were sampled for gene suppression analysis and the remaining treated larvae were placed in pupation medium for 15 days. Emerged adults were collected, counted, and transferred to their respective holding cages and provided standard SCRW dry adult diet with a water source (water agar) until the end of the study period (~ 26 days). Beetle holding cages were kept at room temperature (usually from 22-25 ^°C); 16: 8 dark and light condition with no relative humidity control. After 10 days of preoviposition period, for each treatment the number of male and female pairs was adjusted to 16-20 pairs depending on beetle density and each cage received oviposition dishes and eggs were collected over a period of for 15 days oviposition period, and processed following the method described in Example 2. A set of three males and three females were sampled 10 and 25 days after emergence for gene suppression. Table 4 shows a consolidated summary of egg production, egg hatch and reduction in egg production and fecundity for active WCRW gene targets. Column 1 indicates GOI (gene of interest), column 2 and 3 indicate total egg production/female and total viable eggs/female respectively during the 15 days egg production period; column 4-5 indicate cumulative average egg hatch (± SEM); column 6 and 7 indicates average reduction in egg production (%) (± SEM); column 8 and 9 indicate average net reduction in fecundity (%) (± SEM). Note that values for controls (water and GUS) are cumulative average of 1 1 independent experiments, each run for the duration of 15 days of egg production period.
